ARUNAN, ELANGANNAN (b 1961), Professor, Indian Institute of Science,Bangalore
Member of the NASI: No (YON 2014, Chemical Sciences)
Prof. E. Arunan is an outstanding experimental physical chemist who fabricates specialized equipment to solve difficult and complex problems. The pulsed nozzle Fourier transform microwave spectrometer built in his lab has been used for solving the microwave spectrum of weakly bound complexes formed in a supersonic beam at 3 K. He has shown that both H2O and H2S can form hydrogen bonds (H-Bond), re-writing text books. He effectively combined computational chemistry with experimental results and provided the first dynamic criterion for an H-Bond which had a universal appeal. He eventually formed and led a task group of the International Union of Pure and Applied Chemistry to redefine the H-Bond. Prof. Arunan has become an international authority on hydrogen bonding and other intermolecular interactions and has recently characterized a carbon bond, analogous to the H-Bond. In parallel, he has collaborated with the Aerospace Engineering Department at the Indian Institute of Science to build single pulse shock tube facilities to high temperature chemical kinetics measurements going up to 1500 K. These have been used to resolve longstanding controversy on 1,2-dichloroethane decomposition and study pyrolysis of 2-fluororethanol, a potential CFC alternative. These facilities have also been used to measure ignition delays of fuel which are of interest to national space and defense organizations, such as ISRO and DRDO. He has also led an Indo-French collaboration which resulted in a development of a novel high enthalpy flow reactor. Quality of his publications are much better than what the impact factor of the journals indicate.

BHATTACHARYYA, ANINDA JIBAN (b 1968), Associate Professor, Indian Institute of Science, Bangalore Member of the NASI: No (YON 2014, Chemical Sciences) Dr. Bhattacharyya has made outstanding contributions towards materials for application in electrochemical energy, sensors and photo-responsive devices. He has simultaneously made remarkable contributions towards the critical understanding of materials properties, their correlation with structure and function. Primarily focused on materials synthesis has been on multifunctional high performance soft materials and inorganic/hybrid tailored (nano)structured materials. Few of the polymer electrolytes based on organic liquids (Electrochim. Acta 2008; Electrochem. Comm. 2008), organic-inorganic hybrid electrolytes (Energy Environ. Sc. 2011; J. Phys. Chem. C 2009; Adv. Mater. 2008; Adv. Mater. 2004) and inorganic nanostructured materials (J. Mater. Chem. 2010) have been demonstrated to be potentially attractive for various rechargeable battery chemistries. Owing to the anticipated commercial viability, he has also filed Indian Patents with regard to his works on soft matter electrolytes and nanostructured electrodes. He has also worked on inorganic nanostructures having great potential in solar cells (Energy Environ. Sc. 2013), controlled drug delivery (J. Control. Release 2009), biological/environmental sensors (J. Phys. Chem. B 2009; J. Mater. Chem. B 2013) and photocatalysis (Talanta 2010). Using various spectroscopic, diffraction/scattering (including synchrotron, neutron scattering), electrochemical characterization tools, Dr. Bhattacharyya has convincingly demonstrated interesting confinement effects on organic (bio)molecule structure and function (J. Phys. Chem. B 2012; ChemPhysChem 2014) and charge transport at small length scales (Energy Environ. Sc. 2011; J. Phys. Chem. B 2009; J. Phys. Chem. Lett. 2012). The theoretical interpretations of the materials properties are expected to have far reaching implications in diverse areas of chemical sciences.

Prof. Das’s contribution in ‘biocatalysis within organized assemblies’ is truly a benchmark. He first time showed the importance of ‘space’ for modulating enzyme activity in membrane-mimetic systems (Chem. Eur. J. 2005, 11, 4881). Through rational designing of small amphiphiles, he has developed unique class of self-assembled soft-nanocomposite (Chem. Eur. J. 2006,12, 5068; Langmuir 2008, 24, 4280) with a structure-property relationship for gelation of amino acid-based amphiphiles for diversified applications (Chem. Commun. 2012, 48, 8389; J. Phys. Chem. B 2007, 111, 14107; Langmuir 2009, 25, 8639; Soft Matter 2012, 8, 2348). The amphiphilic hydrogelators exhibited a broad spectrum antimicrobial activity while biocompatible to mammalian cells exhibiting its potential as tissue engineering scaffold (Biotechnology and Bioengineering 2008, 100, 756; Langmuir 2011, 27, 5000-5008; Langmuir 2013, 29, 316-327). His discovery in developing task specific soft-nanocomposite as targeted drug delivery vehicle is remarkable. Prof. Das developed functional amphiphiles for efficient dispersion of carbon nanotube through CNT included self-assemblies (Chem. Commun. 2010, 46, 8386) that are used as target specific intracellular cargo transporters for drug/DNA/protein towards cancerous cells in contrast to non-cancerous cells (Angew. Chem. Int. Ed. 2011, 50, 11243; J. Mater. Chem. B 2014, 2, 1160). This aqueous CNT-amphiphile dispersion comes with huge promise to formulate alternative new age drug delivery systems.

DASS, SAHAB (b 1957), Professor, Dayalbagh Educational Institute (Deemed University), Dayalbagh, Agra. Member of the NASI: No (YON 2014, Chemical Sciences) Professor Sahab Dass has effectively used the principles of Inorganic Chemistry in addressing the problems that are relevant to health, environment and energy. He has made significant and sustained contributions over the last 30 years to environmental pollution and photoelectron catalysis to generate hydrogen using solar energy and water. Starting with an early work on the use of nuclear medicine in labelling anti-bodies and targeting tumour cells, he swiftly moved and got involved in research that focused on toxicological aspects of environment covering important areas that include (a) analysis and control of fluoride in ground water and soil, and its uptake by plants [Water, Air and Soil Pollution (2002)], removal of fluoride from water [Journal of Cleaner Production (2003)], (b) uptake of mercury, cadmium by plants, and (c) heavy metal based pollution of soil, and (d) Removal of aluminium from cookware [Environmental Geochemistry and Health (1997), with relevance to Alzheimer disease. Over the last 15 years, he has developed a strong research program with focus on the photo-electrochemical splitting of water. His group has been involved in developing substitutionally doped oxides [Journal of Physical Chemistry C (2011)] and nanostructured bilayered films [International Journal of Hydrogen Energy (2012)] to effectively use solar energy in generation of hydrogen through water splitting. To understand mechanisms of same, he has recently augmented his research activity with first-principles quantum mechanical calculations. This work is very timely today, and contributes to development of a clean and green fuel for addressing the growing demands of energy.

DATTA, ANINDYA (b 1970), Professor, Department of Chemistry, IIT Bombay, Mumbai Member of the NASI: No (YON 2014, Chemical Sciences) Professor Datta has been working in the area of excited state dynamics in molecules and materials, The major findings of his group are the effect of charged interfaces on the dynamics of excited state proton transfer process, which has been utilized by his group to understand the role of electrostatic interaction on proton mobility within the water nanochannels of nafion, especially at lower hydration level. This is likely to be a first step toward developing a molecular level description of proton conductivity of nafion. He is presently extending these studies to nafion polyaniline conjugates and other membranes like PEDOT/PSS conjugates. Another area where he has made some advances is the study of photoluminescence of silica, where he has demonstrated the existence of emissive trap states in which the trapping process is enhanced by the presence of acids. Presently, he is working on dye-silica nanoconjugates which have potential application as light harvesting antennae. He has also made significant contribution in fluorescence studies of novel organized assemblies like two dimensional lamellar aggregates of aerosol OT, which provide a unique environment for guest molecules and induce unusual dynamics in them. The major scientific contribution is thus the use of excited state dynamics to elucidate complex systems.

GHORAI, MANAS KUMAR (b 1967), Professor, Indian Institute of Technology Kanpur, Kanpur Member of the NASI: No (YON 2014, Chemical Sciences) Prof. Ghorai has been involved in the area of asymmetric synthesis of biologically active compounds by utilizing the concept of memory of chirality (MOC) and chiral pool approach for chiral induction. He has demonstrated the MOC concept in enolate and imino-aldol chemistry for the first time in the country. His research group has conclusively established that activated aziridines and azetidines undergo SN2-type ring-opening reactions in the presence of a Lewis acid producing chiral products contrary to the earlier literature reports involving the intermediacy of 1,3- or 1,4-dipoles which would afford the products in the racemic form. His extensive synthetic, mechanistic and computational studies garnered much scientific deliberation and the groundbreaking finding has paved the way for a new innovative and creative synthetic route towards various non-racemic bio- and pharmacologically active acyclic and cyclic compounds of contemporary interest. Very recently, he has successfully applied the methodology for donor-acceptor cyclopropanes for the stereoselective synthesis of a number of carbacycles. As a part of his interests in stereoselective synthesis of bioactive molecules, he has developed many new domino reactions e. g. domino-imino-aldol-aza-Michael, domino-aldol-Michael, domino-Michael-Michael and domino ring opening cyclization (DROC) of activated aziridines and azetidines for the stereoselective formation of carbacycles and aza/oxa- heterocycles. His research group has efficaciously employed metal- and organocatalysts in the field of domino reactions as well. Overall his research activities including original contributions in the related fields provided new directions to organic synthesis in general and asymmetric synthesis in particular.

The research of Hajra group is toward development of new asymmetric reactions and their applications. The major contributions are divided into three main areas 1,2-Halofunctionalization of alkenes: Prof. Hajra is the first to show Lewis acid catalyzed 1,2-halofunctionalization of alkenes. Asymmetric halohydrination and haloazidation, synthesis of (-)-chloramphenicol, (+)-thiamphenicol and methoxy aminoacids, design and synthesis new chiral halogen source and application to enantioselective chlorination of silyl enolethers, halogen promoted- Friedel-Crafts reaction and one-pot synthesis of 1,5-disubstituted tetrazoles and oxazolines directly from alkenes are some the initial achievements. Asymmetric aldol reaction and synthesis of γ-butyrolactone natural products: Development of first asymmetric syn- and anti-aldol reactions from a same set of reactants by simply inverting the addition sequence of the base and aldehyde is a breakthrough in asymmetric aldol reaction. This method results in direct access to trans- and cis-4,5-disubstituted-butyrolactones. Utilization of the method affords an efficient route toward synthesis of few hundred of biologically active compounds. Syntheses of all (+)- and (-)-paraconic acids and lignans are already achieved. Organocatalytic enantioselective synthesis of butyrolactone has also been developed. Catalytic enantioselective reactions toward synthesis of N-heterocylces: Catalytic enantioselective one-pot aminoarylation via in situ aziridination towards synthesis of trans-1-aryl-2-amino tetralin and its heteroanalogues is another breakthrough from Prof. Hajra group. Concise catalytic enantioselective synthesis of dopamine D1 agonists - dihydrexidine and A-86929/ABT-431 and dopamine D1 antagnists, Sch39166 (ecopipam) are achieved. Recently catalytic enantioselective addition of nitromethane to alkylidene malonates and conjugate addition of aryl boronic acids to dihydronitronaphthalene are also talented contributions.

SURESH KUMAR, GOPINATHA (b 1957), Senior Principal Scientist, CSIR-Indian Institute of Chemical Biology, Kolkata 700032 Member of the NASI: Yes (YON 2014, Chemical Sciences) Dr. Kumar has made extensive spectroscopic and thermodynamic studies to reveal many novel features of the binding of several alkaloids, drugs and dyes (including some of their analogs) with nucleic acids (DNA, RNA) of different structures (e.g., single or double stranded; triple helical or quadruplex etc.) and different sequences, and model proteins (hemoglobin and lysozyme). In each case the details of the binding like binding parameters, thermodynamics, optimum conditions have been thoroughly characterized and recorded in numerous profusely cited publications in high impact journals. He unraveled the chemistry of the interactions of alkaloids like berberine, sanguinarine and their analogs, and dyes like methylene blue, quinacrine, phenosafranine to various polymorphic nucleic acid structures. Specifically, his studies have i) elucidated for the first time the base sequence specificity of binding of these small molecules, ii) discovered a new Hoogsteen base paired left handed double helical (HL-form) DNA structure, which was subsequently confirmed by others, iii) elucidated for the first time the detailed RNA binding aspects of these molecules to provide the fundamentals of RNA interaction, iv) demonstrated for the first time that planar alkaloids bind strongly to single-stranded polyadenylic acid inducing a unique and novel self-structure through adenine-adenine pairing and v) elucidated the binding to model proteins like serum albumin, hemoglobin, lysozyme providing structural and thermodynamic correlation of small molecule-nucleic acid and protein interactions. His work has advanced the fundamentals of binding that are very likely to open a new chapter on the use of these molecules as chemotherapeutic and anticarcinogenic agents.

Dr. Ravikanth’s group contributed extensively to the chemistry of core-modified porphyrins and developed various strategies to synthesize functionlized core-modified porphyrins, core-modified phlorins, β- and meso- substituted core-modified porphyrins and several types of unsymmetrical porphyrin arrays such as porphyrin dyads, triads, tetrads, pentads, hexads including photonic wires containing one or more core-modified porphyrins as constituted elements. His group also involved in the synthesis of new expanded porphyrhyrin macrocycles, non-metal complexes of corroles, metal complexes of core-modified porphyrins and several new functionalized boron-dipyrromethene dyes (BODIPYs) for sensing applications. Some of the important contributions are briefly outlined below: Functionalized core-modified porphyrins, covalently and non-covalently linked porphyrin arrays: Ravikanth’s group developed simple synthetic strategies to synthesize mono-, di-, tri- and tetra- functionalized core-modified porphyrins (JOC-2004, 69, 6796; EJOC-2007, 1168). The functionalized porphyrin building blocks were used to construct several types of covalent and non-covalent multiporphyrin arrays (Chem. Commun-2006, JOC-2008, Chem. Eur. J (CEJ)-2009, IC-2010, IC-2011, CEJ-2012, CEJ-2014). The developed chemistry in this lab was periodically reviewed (Co-ord. Chem. Rev. (CCR)-2006, CCR-2011, CCR-2012). Metal complexes: First Re(I) complexes of core-modified porphyrins (IC-2012, IC-2014), first examples of highly fluorescent P(V) complexes of corroles (CEJ-2012), new core-modified corroles (Org. Lett.-2013), first examples of BF2-complexes of smaragdyrins were synthesized and used for various applications (JOC-2011, Acc. Chem. Res.2012). BODIPYs: Several new functionalized BODIPY dyes are prepared to construct several BODIPY based assemblies (JOC-2011, 8466; JOC-2011, 7263; JOC-2012). BODIPY based sensors were developed and demonstrated their specificity for particular anions and cations (IC-2011, IC-2013, IC-2014, JMC C- 2014).

MURUGAVEL, RAMASWAMY (b 1964), Professor, IIT-Bombay, Mumbai
Member of the NASI: No (YON 2014, Chemical Sciences) Murugavel has made significant contributions to inorganic and materials chemistry by synthesizing soluble models for silicate and phosphate materials, realizing designer zeolites, and unraveling coordination behavior of heavier s-block elements. He has reported the only organic soluble silicophosphonate in the literature and also developed thermally unstable precursors for ceramic phosphates. The reports on benzene tetracarboxylates and systematic studies on group 2 amino/ mercaptobenzoates by Murugavel were the first publications involving these systems in the literature (Inorg. Chem. (a) 2000, 39, 1381; (b) 2001, 40, 6870; Dalton Trans. 2002, 34). The work on the use of hydrolytically and thermally unstable phosphate molecular precursors, developed for the low temperature synthesis of fine particle metal phosphate and silicate materials (Inorg. Chem. (a) 2001, 40, 427; (b) 2002, 41, 6404; (c) 2004, 43, 7585; (d) 2005, 44, 6314) has been well received in the literature with a combined citation of more than 200 in the last five years. The very recent work on the use of metal-monoaryl phosphate systems in building designer zeolites through covalent and non-covalent approaches has been recognized as a major contribution to chemistry of porous materials (Angew. Chem. Int. Ed. 2006, 45, 5536 & 2006, 45, 7022; Chem. Euro. J. 2008, 14, 3869 & 2010, 16, 994, Inorg.

Member of the NASI: No (YON 2014, Chemical Sciences) Dr. Sandip Kumar Nayak has developed several synthetically useful reactions using various transition metal based catalyst. To this end, his contribution in formulating several low-valent titanium (LVT)-based reagents has great impact in the area of selective organic transformations. His work on the modulation of the activity of LVT reagents has led to a conceptual advancement in modern organic synthesis. He has demonstrated the applications of these reagents in the synthesis of various O/N heterocycles and polycyclic aromatic hydrocarbons. Of late he has used LVT chemistry in the synthesis of homocalixarenes for their potential use as metal selective ionophores which has great relevance in nuclear waste management programme. In the past few years, Dr. Nayak has skillfully used the expertise of basic research to the applied areas. In this endeavour, he has accomplished the synthesis of different exotic macrocyclic hosts viz. calixarenes, calixcrowns, cucurbit[uril] etc., which have multifarious nuclear and non-nuclear applications in separation science. In material chemistry research, he has developed efficient strategies for the syntheses of symmetrical and unsymmetrical porphyrins, bis-porphyrins and phthalocyanines that are being used in the design of functional materials for applications in molecular electronics, selective gas sensors and organic magnets. Presently he is leading a group of scientists, working on the development of efficient ionophores for selective removal of radioactive metal ions. In addition, he is associated with several other important activities of Human Resource Development Division of the department including selection, taking theoretical and practical classes for the chemistry trainees.

Micelle-Templated Siliceous, non-Silicieous mesoporous and organic-inorganic hybrid mesoporous materials are important in many fields of materials reaserach, especially for hosting catalysts in confined space. Among this class, the recent discovery of periodic mesoporous organosilica (PMO) represent an exciting new group of organic-inorganic nano-composite targated for a broad range of applications ranging from catalysis to microelectronics. Thus, Vanadium and Chromium containing ethane-silica hybrid mesoporous silsesquioxane with uniform hexagonal arrangement were prepared using C18-alkyltrimethyl ammonium surfactants under basic conditions (A.P Singh et al. Micro & Meso. Mater. 2006, 94, 127; 2007, 99, 334). Further, heterogenized organocatalysts like Mn(III) based binaphthyl Schiff-base complex, Chiral Vanadium-Indanol complex, phosphine free SBA-15-EDTA-Pd highly active recyclable catalyst, Mo(VI)O2@SBA-15, Ru and Fe complex of diamine were synthesized by the covalent anchoring over modified mesoporous surfaces of SBA-15, MCM-41 and PMO (A. P Singh et al. Micro & Meso. Mater., 2013, 170, 331; Appl. Cat. A: Gen.,2012, 439, 101; RSC Advances, 2014, 4, 14073; J. Mol. Cat., 2005, 241,79). In addition, non-siliceous mesoporous Zirconia (Zr-TMS) was also synthesized and organofunctionalized by trifluoromethane sulfonic acid, benzyl sulfonic acid and organosilanol sulfonic acid for various acid catalysed reactions (A. P. Singh et al. J.Cat., 2003, 220, 442; Catalysis Today, 2004, 97, 233). Zeolites were also synthesized for halogenations and acylation reactions. The notable achievements of the nominee are the development of solid recyclable catalyst for the chlorination of toluene to para-chloro toluene and isomerization of orthodichlorobenzene to meta-dichlorobenzene. Both processes were demonstrated to the industries. The technology award was given by the NCL Research Foundation to the development of catalyst for the isomerization of ODCB to MDCB.

VOMMINA, SURESHBABU VENKATA (b 1961), Professor in Chemistry, Bangalore University, Bangalore Member of the NASI: No (YON 2014, Chemical Sciences) Dr. Sureshbabu’s contributions to peptide chemistry include a) development of new peptide coupling methods and reagents, b) total synthesis of peptide natural products and c) synthesis of peptidomimetics. He has developed base-free non-Schotten-Baumann condition for rapid, racemization free peptide synthesis with Fmoc acid chlorides mediated by Zn dust/HOBt derivatives. The procedure has been successful in difficult coupling of dialkyl amino acids and also employed in total synthesis of cyclosporin-O, a challeging cyclic undecapeptide with N-Me amino acids. He has assembled large GPCR fragments using Native Chemical Ligation. Understanding the ‘Fmoc effect’ towards stabilizing α-amino functionalized reactive intermediates led him to synthesize Fmoc-α-amino alkyl isocyanates as new building blocks for peptidomimetic synthesis. Fmoc-α-oligopeptidylureas, ureido and retro-inverso peptides were synthesized employing these isocyanates. Formolysis of isocyanates has yielded new classes of formamides which have been converted to another hitherto unreported class of chiral Fmoc-amino-alkyl isonitriles that are employed in multicomponent reactions leading to new peptidomimetics. He achieved the first synthesis of isothiocyanates and isoselenocyanates derived from amino acids and employed them in the assembly of dipeptidyl thio and selenoureas which are the first examples of the kind. His recent contributions involve demonstration of selenium chemistry in peptides and peptidomimetics and one such important example being synthesis of selenoxopeptides. Diffraction studies of Boc-Phe/Gly-ψ[CH2NCS], Boc-Phe/Gly-ψ[CH2NCSe] and Boc-Phe-ψ[CH2NC] represent pioneering analysis of the crystal structure of building blocks in peptidomimetic synthesis. He has impressive publication record including review articles and is a prolific researcher of his time who has made outstanding contribution to peptide synthesis in the country.

BASKARAN, SUNDARABABU (b 1961), PROFESSOR, INDIAN INSTITUTE OF TECHNOLOGY-MADRAS, CHENNAI Member of the NASI: No (YON 2013, Chemical Sciences) The research activities of Dr. Baskaran are mainly focused on the development of new synthetic methods and explore their applications in the stereoselective synthesis of biologically active molecules. His research group has developed a novel and general method for the stereoselective construction of azabicyclic ring systems based on epoxide-initiated cationic cyclization of azides. He has exploited the synthetic potential of this new methodology in the stereo- and enantioselective total synthesis of many indolizidine and pyrrolizidine alkaloids. The scope of this methodology is further extended to hitherto unknown domino epoxy-olefin-azide cyclization. Moreover, he has successfully developed a semipinacol-Schmidt reaction based domino cyclization strategy for the construction of bridged as well as angularly fused azatricyclic ring systems bearing aza-quaternary centre. His continued interest in the stereoselective conversion of carbohydrate molecules into biologically active and pharmaceutically important molecules has resulted in the development of novel methods for the regioselective reductive as well as oxidative cleavage of bis-benzylidene acetals of D-mannitol leading to highly functionalized chiral intermediates. These functionalized chiral intermediates have been successfully exploited in the diversity oriented synthesis of biologically important iminosugars. Very recently, his research group has investigated the deep eutectic mixtures as novel and environmentally benign reaction media in organic synthesis. Consequently, several synthetically useful and efficient transformations have been achieved using low melting mixtures.

BHARATAM, JAGADEESH (b 1964), Sr. Prinicpal Scientist, CSIR-Indian Institute of Chemical Technology, Hyderabad
Member of the NASI: No (YON 2013, Chemical Sciences)
Dr. Jagadeesh has made very significant and important contributions to the field of structural/analytical chemistry. The notable contributions include, (i) Development of novel NMR methods for solving structures of complex organic molecules in solution as well as solid-state, including dynamics in ultra-thin polymer/lipid films: He was the first to demonstrate the importance of RDC-enhanced NMR for precise determination of secondary structures in designed organic molecules (JACS-2009). Subsequently, this versatile approach has also enabled unambiguous and simultaneous determination of conformation/configuration in multiple-stereocentre drug/organic molecules, with improved accuracy (J.Molec.Struc-2013) (ii) Devising new NMR-methods that accomplish dramatic enhancement in the spectral-resolution even at low magnetic fields, thereby resulting in the simplification of complex spectra (MRC-2014). Dr. Jagadeesh’s other core contribution is the design and development of small biomolecular mimetics that adopt protein-like folding, which has also attracted international appreciations in the field of foldamers. His perceptive design strategies by using quantum-mechanical calculations and NMR experimental studies (JACS-2004;JACS-2005;JACS-2009;Chem.Comm-2006(2);Chem.Comm-2007;Chem.Comm-2010;Chem.Euro.J.2009;Chem.Asian.J-2013) have resulted in novel molecular scaffolds and provided insight into the preferential folding/unfolding mechanism of natural biomolecules, backbone regulation, including the Amyloidal type aggregation/inhibition (Alziemer type). These designs have formed basis for developing function-oriented scaffolds with drug molecules as side-chains. Further,the unique expertise of Dr. Jagadeesh in the area of NMR of large objects (inside-out NMR) and NMR-instrumentation, has lead to a successful implementation in strategic defense programmes. The outstanding scientific contributions of Dr. Jagadeesh richly merit the Fellowship of the National Academy of Sciences and I recommend his candidature in strongest terms.

Dr K V R Chary is presently working as Senior Principal Scientist at CSIR-Indian Institute of Chemical Technology in the area of heterogeneous catalysis. He has received CSIR Young Scientist award and Andhra Pradesh Academy of Science Young Scientist Award in 1989. He has also received, JSPS invitation fellowship, CNRS visiting scientist fellowship, University of Queensland visiting professor, Brain Pool Fellowship from South Korea, Royal Society of Chemistry Journals grant and Raman Research Fellowship as recognition of his outstanding contributions in the area of catalysis. I am personally acquainted with his scientific work and he has published about 100 research papers and supervised 16 PhD students and currently supervising 12 students. Determination of the number and the percent exposure (dispersion) of active sites is one of the most important aspects in designing heterogeneous catalysts. For a given catalyst, the more the number of active sites the better is the yield of the product. Selective chemisorptions of the gases is the most commonly used technique for the determination of dispersion. For the first time the nominee has developed a facile selective chemisorptions method for finding the dispersion of active phase in supported vanadia and molybdena catalysts used in oxidation and hydrotreating catalysts. This methodology has been substantiated by an array of complimentary spectroscopic and surface science techniques. This work enables establishment of structure activity relationships in catalysts to help development of environmentally begin and economically viable processes. Further, the research work of the nominee helped to understand the role of various metal oxides towards selective oxidation/ ammoxidation functionalities.

Member of the NASI: No (YON 2013, Chemical Sciences)
The scientific contributions made by Dr. Atul Goel and his group in developing new fluorescent organic dyes have been highly appreciated by scientific community. Innovatively, Goel et al. have demonstrated for the first time a novel ‘concept’ of inhibiting “Green Emission Defect” in fluorene-based OLEDs by transforming “green” fluorenone molecules to “blue” fluorenone compounds by appropriately swapping of donor-acceptor and chromophoric groups onto widely used fluorene/fluorenone pi-conjugated system (Goel et al. PCT patent WO/2009/122445 dated 08.10.2009; Organic Letters, 2009, 6, 1289; Organic Letters, 2008, 10, 2553). They have successfully demonstrated commercial applicability of these dyes by preparing fluorescent electronic displays, which have opened new vistas in the field of organic electronics. They have shown that emission color can be effectively controlled from ‘blue to green to yellow to red’ by modulating the aromatic pi-characteristic not only in solution (photoluminescence) but also in solid electroluminescent devices (Goel et al. J. Mater. Chem. 2012, 22,14880). Recently they reported a novel donor-acceptor fluoranthene dye FLUN-550 for selective fluorescence staining of cytoplasmic lipid droplets in 3T3-L1 pre-adipocyte cells, in Leishmania donovani parasite and in soil nematode C. elegans for live cell imaging applications in chemical biology (Goel et al. Patent Appl. No. 807DEL2013 dated 19/03/2013; Goel et al. Organic Letters, 2014, 16, 756-759). In the perspective of his contributions for drug development for mankind, his research group identified a new orally active potent fracture healing compound CSIR-CDRI S007-1500 (Pteroheal), which is in pre-clinical drug development stage and under negotiation for licensing agreement (Goel et al.: PCT/IN2009/000285 dated 14-05-09).

It gives me great pleasure in nominating Dr Palakodety Radha Krishna as the Fellow of National Academy of Sciences, Allahabad. He is a devout and versatile organic chemist with varied experience in synthetic organic chemistry. His research interests includes diastereoselective Baylis-Hilman reaction and its application in organic synthesis, isonitrile based multicomponent reactions (IMCR), target-oriented synthesis of bio-active natural products and development of new synthetic methodologies using TosMIC and EDA (ethyl diazoacetate). As a senior colleague, he guided 37 students and has 23 Ph.Ds to his credit. He has 151 research publications, 14 International Patents, 4 review articles and 3 Book-Chapters to his credit. His innovative efforts gave a new dimension to Baylis-Hillman reaction. He introduced novel chiral aldehydes as electrophiles in Baylis-Hillman reaction; brought in the concept of ‘double asymmetric induction’ as a strategic tool for achieving higher stereoselectivities; introduced intra-molecular BH-reaction that resulted in reversing the stereoselectivities with high diastereomeric ratios (>97%). Furthermore, small molecule catalysis is deftly demonstrated in enantioselective Baylis-Hillman reaction. He ingeniously developed newer uses of TosMIC and EDA (ethyl diazoacetate) reagents for generating diverse scaffolds/building blocks. Total syntheses of several bioactive natural products were accomplished by his group. He played a major role in consolidating the bilateral collaborations with Universite of Rennes 1, Rennes, France; RMIT University, Melbourne, Australia and LMU, Münich, Germany. His extensive work in Drug Discovery resulted in IICT-TA67 (PDE4/ICAM-1 inhibitor) with excellent bio-assay profile, currently under clinical trials now. His expereince in Pharma, Agro and Fragrance chemicals {Collaborators: [a) new/process routes: CytoMed/Leukosite, USA; Givaudan, Switzerland; b) solid/solution phase combinatorial chemistry: Glaxo SmithKline, UK; ArQule, USA; c) NCEs: Ranbaxy, India] resulted in high chemistry and revenues.

For a molecular system involving three or more atoms, involvement of multiple excited electronic states in chemical or spectroscopic processes is ubiquitous. On the electronic structure part, construction of potential energy surfaces and their coupling becomes a major task as one has to take electron correlation into account and devise suitable diabatic electronic ansatz to perform nuclear dynamical studies. In the latter, the theoretical approach goes beyond Born-Oppenheimer approximation and electronic and nuclear motions need to be treated concurrently and ideally the treatment should be fully quantum mechanical. Mahapatra and his group is focusing on these aspects of theoretical chemistry and they develop methods and algorithms to treat the emergent problems in the area of relevance in molecular physics & chemistry astrophysics, astronomy and molecular biology. The novel feature of Mahapatra’s approach is a focus on the most crucial quantal effects, also considering in addition to electronic coupling the spin-orbit and Coriolis coupling whenever they are significant. The impact of Mahapatra’s work is clearly fundamental, attempting to devise advanced theoretical models and algorithms to understand basic molecular processes being investigated in modern experiments in spectroscopy and chemical reaction dynamics. Mahapatra has initiated research in this exciting area and has made outstanding contributions from this country. He has published prolifically in the top national and international journals of chemical physics and physical chemistry. He is clearly identified as one of the competent chemical theorists in the country, and we have great expectations from his future development and strongly recommend him for the fellowship of NASI.

MOHAN, DINESH (b 1968), Associate Professor, School of Environmental Sciences, Jawaharlal Nehru University, New Delhi 110067 Member of the NASI: No (YON 2013, Chemical Sciences) Dr. Mohan has made pioneering contributions in the field of water and wastewater remediation of priority pollutants, biofuels development from lignocellulosic biomass and climate change mitigation. He significantly contributed (i) in remediating As, Cr, TCE, F, pharmaceuticals by developing low cost technologies and (2) biomass conversion into biofuels. Agricultural residues which were converted into bio-oil fuels decreases net CO2 release to the atmosphere since new biomass growth for fuel production removes CO2 from air. Biomass conversion into biochar followed by its application to the soil increases the carbon residence time in the soil relative to the application of the same biomass directly to the soil, and considered for CO2 mitigation. Biochar applied to soil also reduce nitrous oxide or methane emissions from soil. Dr. Mohan has been investigated these biochars for atmospheric CO2 mitigation and as green adsorbents without further modification to provide a value added byproduct outlet. He has published > 75 papers in top notch high impact factor Journals. The total Impact Factor of his published papers is >200 while the total citations received so far are >9200 (h factor of 39). Dr. Mohan has been recognized nationally and internationally as his 6 papers have been chosen and ranked very high in the highlights of the 70 years of OUTSTANDING SCIENCS IN INDIA published by CSIR. He was awarded the 2007 Scopus Young Scientist Award (by Elsevier) as the outstanding young scientist. Recently, he has also received Hiyoshi Environmental Award 2009 (by Hiyoshi Corporation Japan).

MOHANTY, JYOTIRMAYEE (b 1971), Scientific Officer (F), Bhabha Atomic Research Centre, Mumbai Member of the NASI: No (YON 2013, Chemical Sciences) The nominee, Dr. J. Mohanty has made significant contribution in the exciting area of supramolecular photochemistry, with an aim to develop molecular recognition-guided functional assemblies based on non-covalent molecular interactions, their specific response to external stimuli and their applications. Employing supramolecular strategy, Dr. Mohanty has shown enhanced photostability of technologically important rhodamine dyes with cucurbit[7]uril in water (US Patent, US7511284B2, 2009) and have been applied to demonstrate highly efficient water-based supramolecular dye laser systems with better thermo-optical properties, environmental and safety benefits, by avoiding the use of volatile/hazardous organic solvents (ChemPhysChem, 11, 2010, 3333; ChemPhysChem, 8, 2007, 54). In a pioneering work, she and her co-workers have established novel tunable supramolecular capsule and fluorescence on-off sensor using cucurbit[7-8]uril, and thioflavin-T (ThT) dye, that responds to metal ions (J.Am.Chem.Soc., 2010, 132, 1395; Chem.Eur.J., 2009, 15, 5215). Exploiting supramolecular pKa shift, a biologically potential dye, neutral red, has been relocated from cucurbituril cavity to a biomolecular pocket by changing the ionic strength of the solution, showing promise for drug-delivery applications (Chem. Commun., 2008,3681). Establishing a supramolecular enhancer strategy for a dye-protein complex (Angew.Chem.Int.Ed.,46,2007,4120), Dr. Mohanty and her coworkers have demonstrated the dual role of Thioflavin-T/Malachite Green dye as an efficient inducer and selective fluorescent sensor for the human telomeric G-quadruplex DNAs (J.Am.Chem.Soc., 135, 2013,367; Angew.Chem.Int.Ed., 46, 2007,9305), which have potential in conquering cancer. Of late, they have established the reversible response of the soft cucurbituril-adorned supramolecular micellar structures to thermal-stimuli, which project their utility for on demand smart drug-delivery vehicles (Soft Matter, 2014, DOI:10.1039/C3SM52024B).

Raghumani Singh Ningthoujam has made significant contributions to the chemistry of nanomaterials covering rare-earth doped nanomaterials and application of nanomaterials to cancer therapy. In the area of Rare-earth doped Nanomaterials, for the first time, he has been able to distinguish free water on surface of particles and confined water in pores or interstitial water in hexagonal structure of orthophosphate using NMR technique [Pramana (2013)]. This confined water is not frozen even at -50°C due to less number of H-bonding. For the first time, he is able to prove the stability of water up to 800°C in case of hexagonal phase of orthophosphate [J. Am. Chem. Soc. 133 (2011) 2998; ibid 132 (2010) 2759]. He is able to perform luminescence On-Off on LaPO4:Tb3+ co-doped with Ce3+ through redox reaction. By combining different Ln3+ ions, he is able to get the primary and white colors on different hosts.In the area of Nanomaterials for Cancer Therapy, he has carried out magneto hyperthermia for targeted and controlled drug delivery in cancer therapy using Fe3O4 and La0.7Sr0.3MnO3 MNPs in AC magnetic field. Enhanced drug release at 42-45°C from liposome is found and this is required for killing of cancer cells (human breast (MCF7) and HeLa [J. Mater. Chem. 21 (2011) 13388]. Killing of cancer cells is found up to 70% within 10 minutes. In vivo experiment on mice has been done successfully and tumour growth can be reduced significantly in AC magnetic field. This will be helpful in clinical trials.

PHUKAN, PRODEEP (b 1967), Professor in Chemistry, Gauhati University, Guwahati Member of the NASI: No (YON 2013, Chemical Sciences) As a part of his continuing work on sulfonamide based reagents (JOC, 2006, 71, 7533, TL, 2009, 50, 5083, TL, 2012, 53, 758), Dr. Phukan has developed a new non-catalytic protocol for the generation of nitrene in presence of a base (Chem. Commun., 2011, 47, 2967), which was further utilized for aziridine synthesis. Dr. Phukan also discovered a catalyst-free protocol for the amidation of C-H bonds of alkyl arenes and aldehydes (Chem. Commun., 2012, 48, 5491). This is one of the pioneering reports of non-catalytic pathway for nitrene generation with experimental evidences. He developed a new CoFe2O4-Cr2O3-SiO2 fluorescent magnetic nanocomposite, which exhibit photoluminescence property without the addition of an external marker. This was used for fluorescence imaging detection of cancer-cells (Nanoscale, 2010, 2, 2250) and photocatalytic degradation of organic dyes (JMCatal, A, 2011, 346, 111). He also developed a new type of hydrophilic magnetic nano-catalyst for organic transformations in aqueous medium (JMCatal. A 2011, 339, 24; JMCatal. A 2012, 352, 128). Dr. Phukan also suggested the use of a parameter called “group nucleophilicity (Ng)” for predicting nucleophilicity behavior of organic molecules using DFT (THEOCHEM, 2010, 945, 64). Dr. Phukan published two significant single authored papers at the initial stage of his career at Gauhati University (JOC, 2004, 69, 4005 and TL 2004, 45, 4785). Both papers are considered among top cited papers in respective field

ROY, SUJIT (b 1959), Professor of Chemistry & Dean (Faculty), Organometallics and Catalysis Laboratory, School of Basic Sciences, Indian Institute of Technology Bhubaneswar, Bhubaneswar - 751007 Member of the NASI: No (YON 2013, Chemical Sciences) The nominee has pioneered highly original concepts in “Catalysis for Fine Chemicals” encompassing aqueous/surface organometallic chemistry, and cooperative multimetallic catalysis. He has developed novel strategies for in-situ generation of organometallic reagents via small molecule activation and integrated them into highly selective bond forming reactions including multi-component/cascade/tandem coupling reactions. Diagnosis of reactive intermediates by spectroscopic and kinetic techniques, a key focus of Roy-group, led to the enumeration of new catalytic cycles and organometallic activation pathways. The discovery of Electrophile Assisted Catalytic Decarboxylation by Roy-group is a major breakthrough, bringing the 150-year old Hunsdiecker reaction into catalytic regime for the first time. Using the dual reagent combination of “tin/zinc” and “transition metal”, Roy-group has developed a versatile Two-component Heterobimetallic Catalysis concept into Grignard-Barbier Chemistry for the activation of electrophiles in water/oxide surface. Using nucleophilicity parameter as guide, the group correlated the Barbier-reactivity and selectivity of organometallic reagents. Recently, the nominee has devised a Cooperative Heterobimetallic TM-Sn Catalysis concept for highly efficient and industrially relevant C-H functionalization reactions. This innovative concept provides a powerful strategy towards atom-economic and green synthesis of fully decorated aromatic and heteroaromatic hydrocarbons which are building blocks for synthetic intermediates/molecular materials. The group is also studying traditional metal-based drugs. Prof. Roy has guided 16 Ph.D students, authored 89 journal publications, 5 book chapters, and 10 patents (US, Indian). He is the recipient of University Gold Medal, (1981), CSIR Young Scientist Award (1994), Chemical Research Society of India medal (2005), and a Fellow of the Indian Academy of Science (2008).

SANJAYAN, GANGADHAR JESSY (b 1968), Scientist; National Chemical Laboratory, Pune
Member of the NASI: No (YON 2013, Chemical Sciences)
Dr. Sanjayan - a “CSIR New Idea Fund” awardee (formerly called as CSIR-crazy idea) has pioneered in the design and development of synthetic peptide scaffolds, which may be of use in intervening various protein / cell membrane interactions. Artificial protein mimetics adopting compact conformations have wide range of potential applications. For instance, they may provide tight-binding ligands for a large protein recognition site, unachievable by the traditional small molecule approaches. Dr. Sanjayan’s acclaimed work on artificial peptide based on the acrylamide oligomer platform has attracted considerable attention from peers [http://www.rsc.org/Publishing/ChemScience/ Volume/2006/06/acrylamide_chains.asp]. Remarkably, there are distinctive differences between native protein sheets and the ones discovered by Sanjayan’s group. Whereas the protein β-sheets make use of the hydrogen-bonding interactions from the backbone for molecular recognition events leading to self-assembly, the sheet-mimetic developed by Sanjayan’s group utilizes the amide groups of the side chain to attain its self-assembled structural architecture. This discovery will have a bearing in utility, since such systems will have improved proteolytic stability due to the absence of the native amino acid residues which would be easily cleaved by the proteolytic enzymes. Dr. Sanjayan’s research group has also been highly successful in the design and development of a novel class of synthetic zipper structures (J. Am. Chem Soc. 2013, 135, 11477; Chem. Commun., 2014, 50, 2886). Dr. Sanjayan’s impeccable contributions in the area of biomimetism have been compiled in a recent invited feature review article (Chem Com., 2011, 47, 11593 - featured on the front coverpage).

He has measured/determined thermodynamic properties like excess molar volumes, VE, excess molar enthalpies, HE, excess isentropic compressibilities,, excess Gibbs free energies, GE, excess heat capacities, of binary as well as ternary liquid mixtures comprising of organic liquid or ionic liquid or Biodiesel and analyzed the same in terms of various currents theories of liquid mixtures. He published his first research paper (1) in 1981, in which concept of connectivity parameter of third degree 3x of the constituents of the mixtures (which deals with topology of the molecule) was utilized to develop Graph theory for the first time that describe well the VE and HE of the binary non-electrolyte mixtures. The expression obtained for predicting VE data via this theory was next amended (2) in terms of 3x of the molecule in pure and mixed state. These 3x values were successfully utilized to extract information about the state of components in pure and mixed state (3-10). The topology of the molecules was next utilized to obtain HE and of various binary mixtures (11-15). Topology of molecules has recently been employed successfully to determine activity coefficients, γ along with GE and of binary mixtures (16-22). Prof. Sharma has also extended this approach to determine VE, HE and of ternary mixtures (23-29). In recent studies, he has employed this theory to predict VE, HE and of ionic liquid mixtures (30-34).

Dr. Balasubramanian is one of India's best computational chemists today and is well recognized internationally. He has made significant contributions to the study of chemical matter through construction of realistic models. His research encompasses CO2 sequestration, room temperature ionic liquids, carbonic acid and supramolecular polymers. He employs techniques such as gas phase quantum chemical calculations, ab initio, atomistic and coarse grained molecular dynamics simulations to study in detail, the electronic, intermolecular and long range structure of these materials. Thus, his work spans all the length, time, and energy scales relevant to chemistry. Utilising results from ab initio MD simulations as a benchmark, he has developed an accurate intermolecular potential to model a category of imidazolium based room temperature ionic liquid which is able to predict nearly all its physical properties rather well. Employing a hierarchical approach, he built on the atomistic MD simulations to study the phenomenon of microscale heterogeneity in ionic liquids using coarse grained MD simulations. He has predicted the self-assembly of a class of such liquids to lead to the formation of a lamellar phase, which caught the attention of many leading experimentalists. He has predicted the crystal structure for carbonic acid. He has also embarked on realistic modelling of adsorption of gases such as H2 and CO2 in metal organic frameworks. His research is notable for its realism, originality, solidity, and the diligence to details. He is a pioneer in the field of large scale, realistic simulations of complex chemical systems in India.

BERA, JITENDRA KUMAR (b 1968), PROFESSOR, INDIAN INSTITUTE OF TECHNOLOGY,KANPUR Member of the NASI: No (YON 2012, Chemical Sciences) Prof. Bera and his research group have pioneered the development of bimetallic constructs (M...M) and their utilization in catalysis. Thus, dicopper(I), diruthenium(I) and dipalladium(I) compounds were shown to be excellent catalysts for cycloaddition, carbene transfer and C-C coupling reactions, respectively. The key idea in this research is that metal-metal cooperation influences substrate activation, guides stereoelectronic factors and promotes product elimination in the catalytic cycle. Lessons learnt from these studies are utilized to develop new-generation catalysts for conversion of cheap and abundant small molecules to useful chemicals. Another key area of research that has been championed by Prof. Bera, includes, designed catalysts that feature metal-ligand cooperation. Carefully designed ligand scaffold which holds the metal ion and simultaneously offers proton-acceptor has been devised for bifunctional water activation. Using this principle, hydration, hydrolytic and oxidation catalysts that utilize water as a reagent have been developed. Catalysts that employ hydroxy/hydroxide and amine/amide functionality are developed for activation of alcohol and hydrogen, respectively. The metal-ligand cooperation strategy is exploited in small-molecule-activation chemistry. In addition to the development of catalysts, Prof. Bera has been involved in understanding fundamental processes in organometallic chemistry employing a host of experimental and computational tools. Through such unifying approaches, a clearer understanding of important reactions such as C-H activation has been achieved.

CHAKRABORTI, ASIT KUMAR (b 1954), Professor and Head of Department of Medicinal Chemistry, national Institute of Pharmaceutical Education and Research (NIPER), Sector 67, S. A. S. Nagar Member of the NASI : Yes (YON 2012, Chemical Sciences) Dr. Chakraborti has pioneered by first time revealing the organo-catalytic role of ionic liquids (ILs) as nucleophile-electrophile dual activation via supramolecular assemblies formed by a network of cooperative hydrogen bond and charge-charge interactions representing novel ‘charge-charge-cooperativity’ and ‘charge-charge-assisted hydrogen bond’ providing mass spectrometry-based model for rational selection of ILs as organo-catalysts and predicting selectivity in organic reactions. His works on the role of water as ambiphilic dual activation catalyst through cooperative hydrogen-bond network offer conceptual advancement in understanding the molecular level interaction of water in accelerating organic reactions, find applications in developing novel ‘all-water tandem reactions’ for synthesis of drugs and bioactive heterocyclic scaffolds, and would promote rational design of aqueous organic reactions. He revealed oxygen uptake by surfactants through mass-spectrometric identification of effective catalytic species as non-heme model for dioxygen activation at room temperature for greener aerobic oxidation. The new catalyst model proposed for epoxide-phenol dual activation through synergistic action of PdNP and water via cooperative effect of ‘coordination-anion-π interaction-HB formation’ provides newer synthetic routes of various drugs. He has introduced several concepts: demand-based and single electron transfer thiolate anion generation, radical-cation-radical-anion pair and cation-neutral-anion pair mediated electrophilic activation for chemo/regio-selective functional group interconversion and nucleophile-electrophile dual activation by specific solvation and Li+-coordination for atom economical chemo-selective O-methylation and synthesis of building blocks to generate new chemical entities. He has developed several transition/alkali metal-based catalysts for synthesis of anti-hypertensive drugs and intermediates. The heterogeneous catalyst systems HClO4-SiO2 and HBF4-SiO2 invented by him are used globally for various organic synthesis.

GHANTY, TAPAN K (b 1963), Scientific Officer (H), Bhabha Atomic Research Centre, Mumbai Member of the NASI: No (YON 2012, Chemical Sciences) Dr. Tapan K. Ghanty has made significant contribution in the frontier areas of research in chemical sciences through the development and generalizations of fundamental chemical concepts to large-scale computations leading to the introduction of new concepts and predictions of novel chemical species. He has generalized the concepts of electronegativity, hardness and polarizability, and proposed important models of chemical bond (J. Am. Chem. Soc. 1994, 116, 3953). Polarizability-size relationship (J. Chem. Phys. 2003, 118, 8547) and the “minimum polarizabilty principle” (J. Phys. Chem. 1996, 100, 12295) proposed by him are extremely useful to rationalize various chemical reactions and to predict the polarizability of larger clusters, respectively. Through an in-depth analysis he has elucidated the nature of hydrogen bond in water and ice (J. Am. Chem. Soc. 2000, 122, 1210). He has theoretically designed and predicted several novel molecular species, such as, new rare gas compounds (J. Chem. Phys. 2006, 124, 124304; 2013, 138, 194308). One of his theoretically predicted rare gas compounds, HXeOBr, is synthesized abroad. His recent works on the predictions of nano-size gold clusters are very important in the design of novel cluster-assembled materials (J. Phys. Chem. C 2010, 114, 20; 2012, 116, 193). He has predicted a new class of stable metallofullerenes, which are of immense interest for their potential applications in electronics, optics, bio-medicine etc (J. Phys. Chem. C 2012, 116, 16716; 2012, 116, 25630; 2013, 117, 17859). He is also actively involved in designing actinide-selective new ligands (Phys. Chem. Chem. Phys. 2012, 14, 11060).

Prof. Manoj Kumar designed, synthesized and evaluated a number of fluorogenic receptors based on different scaffolds like (thia)calix[4]arenes, terphenyls, tripheylene, hexaphenylbenzene, hexa-peri-hexa-benzocoronene (HBC) and pentaquinones selective for soft metal ions like Ag+, Cu2+, Hg2+, Pb2+, Zn2+, Fe2+, Fe3+, anions like F-, Cl-, CN-, H2PO4- and nitroaromatic compounds like trinitrotoluene and picric acid. Based on the fluorescence behavior of these molecules a number of molecular switches and chemical logic gates have been reported which mimic the functions of different molecular electronic and photonic devices used for information, processing, sensing and computation. Prof. Kumar also reported two different types of molecular devices, molecular keypad locks based on sequential chemical inputs (which help to protect the information at molecular level) and molecular information storage devices (memory devices). Prof. Kumar also reported energy transfer cassettes (in which donor and acceptor are joined through an aromatic conjugated spacer) which undergo through bond energy transfer in the presence of Hg2+ ions. The biological applications of some of these fluorogenic receptors were tested for in vitro detection of metal ions like Hg2+, Cu2+ and Fe3+ in living cells. Prof. Kumar also reported aggregation induced emission enhancement (AIEE) luminogen system in which six aromatic rotors are joined by benzene ring. Prof. Kumar also reported facile preparation of palladium and gold nanoparticles using pentacenequinone derivatives which exhibited high catalytic activity in comparison to nanoparticles reported in the literature. For his contribution to chemistry, Prof. Kumar was awarded Bronze medal by Chemical Research Society of India (CRSI), Bangalore, in 2011.

MANDAL, ASIT BARAN (b 1952), Director, CSIR Central Leather Research Institute, Chennai Member of the NASI: No (YON 2012, Chemical Sciences) Prof. Mandal is one of the most important contributors to the understanding of micellar systems in India. Modified Huggins-Thomas equation by including a parameter based on both experimental and theoretical investigations led to the equation being termed Huggins-Thomas-Mandal equation. He made significant contributions to the development of new experimental methodologies for characterization of micellar, monolayer and reverse micellar systems involving collagens, peptides, drugs, tanning-materials, macromonomers, Nanomaterials, ionic-liquids, liquid crystals and polymeric systems. These new methods exploited large number of physical techniques including electrochemical, fluorescence and resonance methods. One of his contributions includes design rationale for synthesis of mono-disperse polymers. Innovation has been in assembling macromonomers into a micellar system and initiating polymerization within the micellar cage. His contributions on micellar systems with respect to Electrochemistry, Thermodynamics, Relaxation kinetics, Hydrogen-bonding, Structure-Geometry, Conformations, Molecular dynamics, Solubilization, Location, Solvation behaviour, Monolayer aspects and Diffusional phenomena are quite extensive and well-cited. He made quantification of several parameters in micellar chemistry feasible through applications of rigorous techniques viz. self-diffusion measurements by Cyclic-Voltametry, Chronocoulometry, Square-wave-voltammetry, DLS, SANS and FT-PGSE-NMR techniques to determine hydrodynamic radius of the micelles. He has resolved scientifically some controversial discussions on the feasibility of formation of micelles in non-aqueous solvents using various sophisticated techniques. Recently, demonstrated Loading-unloading processes of acid-responsive Microcapsules with interesting “zip-unzip” phenomenon and click-polymerization. He is a productive scientist, who has contributed significantly to capacity building in the area of his specialization including self-assembly processes. His path-breaking contributions to surface and colloid sciences are valuable and noteworthy internationally

I have visited her department and research laboratories two years back and was quite impressed on the quality of research work going on at her centre. Dr. Menon’s main contribution is to the field of Supramolecular Chemistry and Nanomaterials focusing mainly on the wide variety of applications of these materials newly synthesised. She has worked on the synthesis of all types of functionalized super and supramolecules, namely crown ether calixarene crypt and catanane46, rotaxane and fullerene and have applied for the separation of cations, anions, as sensors, as fluorescent material as ion selective electrodes, as dyes, as catalysts, as liquid crystals, as inclusion medium for insoluble drugs and as drug conjugate. Dr. Menon has published papers out of which 9 are review articles, publications are on Supramolecules or Nanomaterials. Supra-nano assemblies have been synthesised and were used as sensors of K+ in blood, amino acids sulfide and explosives like, TNT; nanomaterials were used for removal and nanoformulations for sensing anticancer drugs. Dr. Menon’s research work is highly consistent and have shown a progression in the quality of research work as evident from the publications in high impact factor journals, throughout her academic career.

Member of the NASI: No (YON 2012, Chemical Sciences) Dr. K. Natarajan and his research group have synthesized many mononuclear and binuclear uthenium(II) and ruthenium(III) complexes containing different types of Iigands such as bidentate Schiff base, tridenatate Schiff base, tetradentate Schiff base, -diketones and bis (-diketones) with monothio, monoseleno, dithio, diseno and methylene bridging units. With the help of the new complexes synthesized, they have studied the effect of different ligands on redox potentials of ruthenium ion. All the new complexes have been screened for their catalytic and antimicrobial activities. In the case of catalytic oxidations, it has been shown that only alcoholic group got oxidized selectively without any change in the double bond present in the substrate. It has also been found that mononuclear and binuclear ruthenium(III) Schiff base complexes serve as catalysts for aryl-aryl coupling reactions. The antibacterial and antifungal activities of our complexes have also been screened. Most of the complexes showed activity against pathogenic microbial. Interestingly, it has been observed that ligands containing sulphur donor exhibit better activity compared to ligands containing O and N donor atom. For past six years, Prof. Natarajan and his team have been actively engaged in the synthesis, characterization DNA binding, Protein interaction, antioxidant and anticancer properties of new copper, cobalt, palladium, nickel and ruthenium complexes containing thiosemicarbazones, semicarbazone, hydrazones and dicarboxylic acids along with some catalytic applications. It is to be noted that a few of the above complexes showed better activity than that of cisplatin, a drug which is currently used clinically for the treatment of cancer.

PRADEEP, THALAPPIL (b 1963), Professor, Indian Instiute of Technology Madras, Chennai Member of the NASI: No (YON 2012, Chemical Sciences) Pradeep’s discoveries in the areas of molecular and nanoscale materials and associated phenomena have implications to clean environment, affordable clean water and ultrasensitive devices. Pradeep discovered several atomically precise clusters or nanomolecules of noble metals such as Ag7/8, Ag9, Au23 and Ag152, smallest molecular alloys such as Ag7Au6, created highly uniform nanotriangles and mesoflowers and developed ultrasensitive single particle sensors, which are probably the limits of molecular detection today. He discovered noble metal nanoparticle-based drinking water purification methods and developed the world’s first drinking water filters utilising nanochemistry. He developed several new technologies in the recent past to tackle various other contaminants in water. Pradeep discovered that binding of metallic nanoparticles on metallic carbon nanotubes made the latter semiconducting and as a consequence, the nanoparticle-nanotube composite became luminescent in the visible region. He showed a ‘transverse electrokinetic effect’ in metal nanoparticle assemblies which resulted in a potential when a liquid was flown over it. Other aspect of his research is on ice, the solid form of water. He showed that vapour pressures of gases oscillate over melting ice. He found that H2+ gets formed when low energy proton (H+) strikes ice, quite unlike its collision on liquid water, where it makes H3O+. To discover and understand such processes, especially at the top of ice, he built the very first ultra low energy ion scattering spectrometer, a new tool in extremely surface sensitive spectroscopy, working at cryogenic temperatures, as in space.

RAMASESHA, SURYANARAYANA SASTRY (b 1950), Institution Professor, Indian Institute of Science, Bangalore
Member of the NASI: No (YON 2012, Chemical Sciences)
Ramasesha developed second quantized valence bond (VB) methods and provided the first numerically exact solutions of the low-lying states of Hubbard and Pariser-Parr-Pople models for polyene chains which have served as benchmark for all further theoretical studies. Using the symmetrized density matrix renormalization (DMRG) methods developed by him and VB technique, he explained the mystery behind crossover from fluorescing to nonfluorescing states in organics. Ramasesha developed techniques to compute exact nonlinear optic coefficients within the VB and DMRG approaches to study the dependence of NLO response on size and topology of conjugation. He developed time dependent VB methods to definitively resolve the puzzle that in OLEDs singlet excitons are formed far in excess of the theoretical limit predicted by spin statistics. Ramasesha pioneered the use of DMRG methods to obtain quantum phases of spin chains with frustrated and dimerized exchange interactions. He has modeled a variety of magnetic phenomena such as quantum resonant tunnelling in single molecule magnets (SMMs), magnetic anisotropy in SMMs, magnetization plateaus in spin ladders, magnetic behaviour of ferrimagnetic spin chains, anomalous exchange interactions in high-nuclearity transition metal complexes and photomagnetism, by developing appropriate many-body models and techniques. The work of Ramasesha has been extensively cited in the field. The techniques developed by him are being used by several groups around the globe. He has been invited to speak and chair sessions at many prestigious international conferences. He has trained a large number of young researchers who now adorn faculty positions in premier institutions around the world.

ROY, SUBHAS CHANDRA (b 1954), Senior Professor & Head (Administration), Deptt. of Organic Chemistry, Indian Association for the Cultivation of Science, Kolkata - 700032 Member of the NASI: No (YON 2012, Chemical Sciences) Radical reactions has opened the door of a new era in recent years for carbon-carbon bond formation and it reflects its significance as a powerful tool in modern synthetic chemistry with high regio- and stereoselectivity. To avoid toxic tin hydrides, C-O homolytic cleavage was successfully performed by RajanBabu and Nugent using bis(cyclopentadienyl) titanium(III) chloride [Cp2TiCl] at room temperature. The reagent can easily be generated in situ from commercially available Cp2TiCl2 and activated zinc dust in THF. This novel method opened up a new era in so called challenging radical controlled reactions. We are one of the leading groups in the world working in this area especially in the stereoselective total synthesis of bio-active natural products and contributed a considerable amount of work for more than two decades or so. We have successfully achieved the stereoselective total synthesis of several anti-tumour antibiotics, naturally occurring lignans, bio-active 3,4-dihydroisocoumarin natural products and challenging fused bis--butyrolatones using titanocene(III) chloride (Cp2TiCl) as a radical initiator in racemic as well as in optically active forms. We have also applied the same radical chemistry for more than a dozen of organic transformations and methodologies of synthetic significance. We have also developed more than two dozen of environment friendly methodologies of synthetic importance using inexpensive non-toxic rack reagents. Some of these methods produced important compounds in only one or two steps such as regio and stereoselective formation of dihydrofurans by oxidative [3+2] cycloaddition, synthesis of fused acetals by cycloaddition of 1,3-dicarbonyl compounds to cyclic enol ethers etc.

SINGH, RADHEY MOHAN (b 1952), Professor and Banaras Hindu University, Varanasi
Member of the NASI: No (YON 2012, Chemical Sciences)
Dr. R. M. Singh is renowned teacher in the chemistry department and one of the leading researchers in reaction mechanism and heterocyclic synthesis. He began his academic career from Banaras Hindu University, Varanasi since April, 1979 and started research with limited facilities and resources. During past few years, Dr. Singh has been actively engaged in the synthesis of carbo-/hetero-fused quinolines using 2-chloroquinoline-3-carboxaldehyde, 3-cyano and 3-ester derivatives. Dr. Singh have synthesized these precursors first time in his laboratory from N-arylacetamides through Vilsmeier-Haack approach (Indian J Chem, 44B, 1868, 2005). His group has reported bidentate phosphine ligand-Pd-catalyzed inter and intramolecular Heck reactions (Tetrahedron Lett, 2014 (in press); Tetrahedron, 68, 9206, 2012) and developed Pd-catalyzed efficient synthesis of pyrano-/pyrido- fused quinolines. (J Org Chem, 74, 5664, 2009; highlighted in Synfacts, 11, 1206, 2009 and in Cheminform, 41, 2010; Tetrahedron, 64, 11680, 2008; Tetrahedron 69, 9443, 2013). Facile/rapid synthesis of biologically active pyranoquinolines has also been developed via intramolecular iodo cyclization reactions of alkenes and alkynes. (Tetrahedron Lett, 48, 5987, 2007; Tetrahedron, 67, 505, 2011). Further, rapid synthesis of benzo[b][1,8]naphthyridines has been developed from Baylis-Hillman adducts via Michael addition and SNAr reactions.(Tetrahedron, 67, 2441, 2011). Rapid domino synthesis of thiopyrano[2,3-b]quinolines has been reported from 2-thione via Michael addition and cyclization reactions.(Tetrahedron Lett, 53, 3242, 2012; highlighted in Cheminform 43, 2012). Recently, his group is concentrating on metal-free reactions and developed base catalyzed and Vilsmeier approach to efficient synthesis of pyrimido[4,5-b]quinoline-4-ones (Tetrahedron, 67, 9219, 2011; 68, 10318, 2012) respectively and facile synthesis of pyrano[4,3-b]quinolin-1-ones in aqueous basic medium (Tetrahedron 69, 1822, 2013).

CHAKRAVARTY, CHARUSITA (b 1964), Professor, Department of Chemistry, Indian Institute of Technology Delhi Member of the NASI: No (YON 2011, Chemical
Sciences) Dr Charusita Chakravarty has made outstanding contributions in theoretical chemistry. Her work on (i) understanding the anomalous properties of water and the associated consequences for hydration in chemical and biological systems, (ii) developing relationships between structure, thermodynamics and transport in liquids, such as ionic melts and polymers and (iii) understanding relationships between single-particle and collective transport properties of network-forming ionic melts, such as SiO2 and LiF-BeF2 are highly significant[2,3,5]. By relating quantitative measures for mobility, entropy and structural order in liquids, she has shown that excess entropy is the critical quantity connecting thermodynamic, diffusional and structural anomalies of such liquids in water, as well as other liquids with water-like anomalies, such as silica and core-softened fluids[1,4]. Dr. Chakravarty has been interested in understanding the collective atomic level reorganisations associated with order-disorder phase transitions, such as freezing, nanoparticle assembly, protein folding and aggregation. She has applied energy landscape analysis to understand phase transitions in both bulk and finite clusters, using quantum and classical simulations[7,9]. She has developed and applied efficient path integral Monte Carlo simulation methods for studying quantum effects in atomic and molecular systems[8]. She has also worked on unusual diffusional behaviour in confining media, such as the levitation effect, diffusional anisotropy and single-file diffusion. Her Ph.D. thesis was on quantum scattering and spectroscopy of van der Waals dimers[10].

CHEPURI, VENKATA RAMANA (b 1968), Scientist, CSIR-National Chemical Laboratory, Pune
Member of the NASI: No (YON 2011, Chemical Sciences)
Ramana is one of the pre-eminent organic chemists of India who can handle the synthesis of architecturally and stereochemically challenging complex molecules with remarkable ease. Ramana’s particular insight into total syntheses was to develop and deploy the transition-metal catalyzed reactions for addressing the C–C and C–O/N bonds inter-alia the skeletal complexity that distinguishes him from the other contemporary synthetic chemists of India. Some of his syntheses are characterized by their modularity (Target-cum-flexibility, a new concept) that enabled the synthesis of focused small molecule libraries. The recent total synthesis of trigonaliimine C and isatisine A by his group are classic examples wherein several [metal]-catalyzed/mediated transformations have been developed and executed in a sequence. This is a rare feat in total synthesis. Complementing this work, he has also developed new concepts/methods which involve the formation and/or reorganization of several C–C and C–O/N bonds in one pot with a single catalyst. TheTiCl3-mediated pincol cum ketalization, the acid-catalyzed “furan-ring transposition” and “double furan-ring transposition” “alkynol cyclization – Kishi reduction” for the C-saccharides synthesis, SNAr–(azide-alkyne cycloaddition), SNAr–azide reduction and SNAr–Smalley cyclization - fall under this category. Recently, he showed that a single [Ru]-catalyst can affect the complementary directed and direct C–H activation of 2-aryl pyridine derivatives in one-pot – which is the first of its kind. Some preliminary, yet important contributions in other areas such as glyconanoparticles, beta-peptides and crystal engineering made by Ramana reveal his ability to ask fundamental questions in areas other than synthesis.

CHATTOPADHYAY, SUNIL KUMAR (b 1952), Chief Scientist, CSIR- Central Institute of Medicinal and Aromatic Plants (CIMAP), P.O. CIMAP, Lucknow - 226015. Member of the NASI: No (YON 2011, Chemical Sciences) Dr. Sunil Kumar Chattopadhyay in a focused way consistently has addressed the problem of drug development technology related to anticancer molecules (Taxol) and Docetaxel (=Taxotere) (US patents 5,856,532; 1999 and 6028,206; 2000). His path breaking approach has not only been innovative but highly significant also in terms of leads obtained particularly from the Himalayan yew Taxus wallichiana. The semi-synthesis route developed by him for the preparation of the anticancer molecule Taxotere is straightforward, high yielding and cost effective. The taxoid brevifoliol isolated and upscaled by his group from the needles of Taxus wallichiana was evaluated to be a very promising anticancer compound based on a non baccatin-III moiety (US patents 7,579,491; 2009 and 7,196,115; 2007). The taxol/taxotere analogs that were designed by him from brevifoliol would certainly make a visible impact in cancer research (European Journal of Medicinal Chemistry, 43:1499-1505 (2008). Dr. Chattopadhyay has isolated and characterized a new class of compounds known as coumarino-lignoids. In in vivo model, it exhibited liver protective activity against phalloidin, carbon tetrachloride and paracetamol induced liver toxicity as comparable to silymarin, the standard drug used to treat liver diseases. The results published on coumarino-lignoids in the reputed journals Tetrahedron, 41: 209-214 (1985); Tetraherdon Letters, 21:4477-4480 (1980) and Heterocycles, 19: 19-22 (1982) have received considerable citations. The natural form of the synthetic anti-aids drug nevirapine has been recently isolated and conclusively proven to be different from the synthetic nevirapine by isotopic ratio mass spectrometry (IRMS).

DAS, PUSPENDU KUMAR (b 1958), Professor, Indian Institute of Science, Bangalore Member of the NASI: No (YON 2011, Chemical Sciences) The Nominee has made significant contribution in the area of laser spectroscopy and dynamics using a variety of techniques involving multiple laser- beams. The Nominee’s work in the area of nonlinear optics in the development and application of the hyper - Rayleigh scattering technique as a spectroscopic tool for measuring physical properties in solution have been widely recognised. He used this technique for measuring dissociation constants of weak acids, partition co efficient of an analyte distributed in two phases, formation and stoichiometry of non - covalent supramolecular structures, CMC of surfactants, multiple binding constants of a small molecule to a macromolecule, and the equilibrium solution geometry of charge transfer complexes. The nominee has recently shown that the local excitation of surface dipoles leads to large optical nonlinearity in noble metal nanoparticles. He has worked extensively in the area of nonlinear optics and developed many interesting problems. His research in the area of chemical dynamics using two crossed ultraviolet laser beams in a “pump- and-probe” configuration has richly added to the understanding of the ultraviolet dissociation pathways in alkyl iodides and bond selective dissociation of polyatomic molecules. Recently he has done some interesting work in the area of infrared spectroscopy of polycyclic aromatic hydrocarbons (PAHs) in the gas phase. He has recorded spectra of some PAHs having very low vapour pressures in a heated long path-length gas cell assigned the spectral lines using state-of-the-art quantum chemical calculations. The Nominee has published more than 100 papers in peer reviewed journals of which more than 40 are in American Society Journals.

GHOSH, SUBRATA (b 1950), Senior Professor, Department of Organic Chemistry, Indian Association for the Cultivation of Science, Jadavpur, Kolkata - 700032 Member of the NASI: No (YON 2011, Chemical Sciences) Professor Ghosh has made significant contributions in the emerging areas of organic synthesis on complex bio-active natural products of contemporary interests. One of his notable contributions is the development of novel routes (first effort reported from India) towards the bridged-ring skeleton of the anticancer drug taxol (TL 1990, 1483; TL 1992, 2363; TL 1993, 2987; Chem.Commun. 1997,2039). The role of copper (I) catalysis in promoting the reactivity and controlling the stereoselectivity in photocycloaddition of unactivated 1,6-dienes has been uncovered by the nominee and has been exploited in the facile stereocontrolled synthesis of a few complex cyclopentanoid natural products (Chem.Comm. 1993, 783;TL 1996, 2073; JOe 1995, 2526; Joe 1997, 5211). This discovery has made a global impact and has been used by other chemists for accomplishing total synthesis of molecules which are otherwise difficult to achieve. He has made impressive contribution in the area of asymmetric synthesis employing nature's chiral pool e.g. carbohydrate. Notable achievements in this area include discovery of economical routes to anti-HIV drug (-)-carbovir (TL 2004, 6457); anti-HIV active BeA (JOe 2005, 4199), anti-inflammatory agent (- )-bacillariolide I (Org. Lett. 2006, 3781) and neurotrophic agent (- talaumidin (TL 2008, 3433). His recent contributions include elegant application of olefin metathesis in developing single-step protocols for accessing the highly complex structures present in natural products such as ingenol (Org. Lett 2007, 2537), guanacastepenes (JOC 2009, 1957), umbellactal, schisandra terpenes (JOC 2010, 4192) etc. His contributions in the domain of natural products synthesis are well appreciated and are amply documented in literatures.

GOSWAMI, DEBABRATA (b. 1964) Professor, Deptt. of Chemistry, IIT Kanpur, Kanpur - 208016 Member of the NASI : No (YON 2011, Chemical Sciences) Right from his PhD days, Prof. Goswami has explored immense possibilities of role of light in furthering existing science and technology (Science(l992) 255:1683-1685). Significant impact of his independent research in several interdisciplinary areas is a result of his original contributions in applying femtosecond lasers for selective photodissociation, microscopy, and quantum information processing. Specifically, his work is at the forefront of the interdisciplinary research area of coherent control, which embodies theoretical and experimental developments in: Programmable Femtosecond Laser Pulse Shaping for nonlinear spectroscopy and their control (Physics Reports(2003) 374:385-481); Thermal-lens spectroscopy (J Phys. Chem. B(2011) 115:262-268); Optical approaches in Quantum Information processing (Phys. Rev. Leu. (2002) 88: 177901); as well as novel enhancements in bio-imaging, superresolution microscopy and spatiotemporal control in nanoparticles (lRPC(2011) 30:275-299). His independent research spanning over the past one and a half decades have been carried out in the self-made and self-sustained laboratories that he has developed in India in spite of any technical and infrastructural support. Incidentally, he was the first to propose how the phase of a laser pulse can be critical in Quantum Computing and the experimental approaches to adiabatic quantum computing in analogy to the coherent control approaches. Given his experimental acumen, he constructed several versions of tunable and programmable femtosecond pulse shapers in our laboratory-the latest one being a Genetic Algorithm Scheme for the Fourier Transform based acousto-optic modulator pulse shaper. The present recommendation is based on such seminal contributions of Dr. Goswami towards optical approaches to quantum computing and non-invasive medical technology.

KOLANDAIVEL, PONMALAI GOUNDER (b 1956), PROFESSOR AND HEAD DEPARTMENT OF PHYSICS, BHARATHIAR UNIVERSITY, COIMBATORE Member of the NASI: No (YON 2011, Chemical Sciences) Dr. Kolandaivel has made significant contributions in conceptual density functional theory, hydrogen and halogen bonding interactions, bionanotubes, charge transport through peptides and molecular dynamics. Paul Geerlings an authority in this field has quoted in different places (Chem.Rev, 101 (2001) 1451; 103 (2003) 1793), the importance of Kolandaivel’s work on chemical reactivity parameters, isomer’s stability by chemical hardness and the relation between force constant and hardness. The comprehensive study on the above subject is considered as one of the landmark contributions of Dr.P.Kolandaivel in conceptual density functional theory. His claim that the intramolecular charge transfer is also one of the reasons; in addition to the charge transfer from the proton acceptor to the proton donor molecules for the blue shift hydrogen bond has been accepted world wide by the active researchers in this area. The cyclic peptide has been used to construct few nanotubler structures and studied the structure, interaction and dynamics of the nanotube. Dr. Kolandaivel has successfully attempted to fine tune the structure for the biomedical applications of bionanotubes. The study of interaction of drug molecules with usual and mismatch base pairs of DNA molecule helps to understand the inhibiting nature of cancer cell growth. The role of secondary structures, change of dihedral angles due to rotation and the presence of intramolecular hydrogen bonding are the important parameters to control the charge transfer mechanism in the polypeptides have been established. Prof. Schlag inventor of ZKES spectroscopy who with Baranov who had also got this result recently when came across Dr. Kolandaivel’s work wrote that he was surprised to note this findings to compliment their exciting results.

Cement, indispensable in nuclear energy programs for immobilization of non heat-generating low-level radioactive waste, is ubiquitous material. The complex Chemistry including the role of hydrogen bond of hydrated cement is still poorly understood. Dr. Mazumder’s research, with broader interest on the mechanism of cement hydration, indicated the upper limit on the amount of non-heat generating low-level radioactive waste that can be incarcerated safely in cement matrix. His research results are used in practice in DAE. He has given a partial mechanism illustrating temporal evolution of mesoscopic structure, as revealed by analytical technique, small-angle neutron scattering (SANS), of hydrating cement paste. His work on cement hydration is a step forward in understanding the mechanism of cement hydration. For necessary experimental support, Dr. Mazumder has developed two SANS instruments to access wider length scale. Instruments are presently used for characterization of some advanced ceramics, hydrated cement composites, special steels and other materials of technological importance. Further, he has also developed a formalism, required to analyse SANS data from strongly scattering system like cement matrix, on multiple small-angle scattering accounting for polydisperse statistical nature of the medium. He has shown that there are two distinct mechanisms and time-temperature-transformation curves for precipitation, one below and the other above the age-hardening temperature of maraging steel. He is currently building a small-angle x-ray scattering facility in INDUS-II. He has served several International Committees for SAS in IAEA, SAS-2009 (www.sas2009.org) in Oxford, for SAS-2012 (www.sas2012.com) in Sydney and SAS-2015 (www.helmholtz-berlin.de/events/sas/ ) in Berlin.

PALANIANDAVAR, MALLAYAN (b 1951), Professor of Chemistry & DST Ramanna National Fellow, Department of Chemistry, Central University of Tamil Nadu,Thiruvarur 610 004,Tamil Nadu Member of the NASI: No (YON 2011, Chemical Sciences) Professor Palaniandavar has made outstanding contributions through studies on DNA binding and anticancer activity of Cu(II) (IC 2009, 2011, 2012; Dalton 2010), Fe(II) (Dalton 2011), Co(II), Ni(II) (Dalton 2011) and Ru(II) complexes of diimines (IC 2008). He has performed outstanding studies on Cu(II) and Ru(II) complexes of diimines bound to DNA and polynucleotides and made the `fascinating discovery’ of left-handed Z-conformation of DNA (Chem. Comm. 1996, IC 2007). He has constructed structural and functional models for dioxygen-activating catechol dioxygenase (IC 2008 - 1998, Dalton 1998 - 2011), methane monooxygenase (Dalton 2009, 2009) and galactose oxidase enzymes (Dalton 1992, 1994). Exclusive extradiol cleavage of catechol has been achieved for iron(III) complexes in non-aqueous (IC 2007 - 2010) and aqueous micellar media (Dalton 2010, 2011). He has devised the first structural model containing axial Cu(II)-phenolate bond to illustrate the influence of axial ligation on GOase activity (IC 1998, Dalton 2001). He has demonstrated the contribution of copper(II) geometry and coordinated thioether to the facile electron-transfer of blue proteins (Dalton 1992, 1994, 1996). He has isolated rare five-coordinate iron(III) (IC 2003, Dalton 2010) and trigonal planar copper(I) (IC 2001) complexes, which constitute his outstanding contributions. He has established the relationship between Cu(II)/Cu(I) redox potential and axial distortion (Dalton 1995). He has discovered the uncommon see-saw stereochemistry of a copper(II) complex (Dalton 2000), the unusual facial coordination of a triaza ligand (Dalton 1995), the simultaneous coordination of four cytosine molecules (Dalton 1996, ICA 2002) and secondary sphere coordination of cyclodextrins to copper(II) (Dalton 1996).

Synthesis and application aspects of organic nanomolecules and to be very specific cyclophanes and dendrimers are focussed. Cyclophane chemistry was at the beginning stage during 1998 when we started our work in this area. It is our group which started to synthesis cyclophanes with rigid cavity. The advantage of having aromatic building blocks for the synthesis of cyclophane is in many fields. New class of Novel cyclophanes were synthesized during the past 20 years. Some of the cyclophanes are used as ion filters anion sensors, Molecular channels due to self assembly and selective metal ion chelation of Cu2+ & Pb2+ in a mixture. Synthesis and bioactive properties like antifungal, antibacterial, anti-inflammatory, anti arthritic and antioxidants behaves of various dendrimers with higher generation has been studied. Soon after exploiting the application of cyclophane we focused our attention on the synthesis of dendrimer. Dendrimer are spherical molecules with tree like structure. The three sections of the dendrimers are core unit, branching unit and surface group. Hence variation can be given to any one unit and change in property can be studied. In the current investigation we have used various core units which are biologically and electrochemically active and studied their electrochemical and biological activity. Recently various glycodendrimers were synthesized and their ability for anti diabetic activity has been tested cell line studies were also carried out with some glycodendrimers as preliminary test for anti cancer activity. Further some of the dendrimers show good efficiency in harvesting solar energy and hence used as additive for DSSC.

SHARMA, RAJ PAL (b 1950), Professor. and Department of chemistry, Panjab University, Chandigarh-160014 Member of the NASI: No (YON 2011, Chemical Sciences) Professor Raj Pal Sharma with an illustrious teaching career has made original research contributions in a number of diversified areas encompassing inorganic, solid-state and crystal engineering interface. The focal theme of the work is: • Second Sphere Interactions: The ability to impart requisite selectivity and sensitivity in complex systems such that they become stable and isolable in condensed phase has been explored. It has been found that, along with charge and size complementarity of the counter ions, it is essential to consider the cooperative lattice stabilizing ability of weak interactions.12,30,35,37,41,48-50,53,55,58,111 • Crystal Engineering: The structure directing influence of non-covalent interactions and their influence in generating well recognized association patterns and networks has been incisively studied in a number complexes. These studies delineate that the ‘rosette’ formation, the ‘bi-layered’ association of ions, patterns such as ‘rings’ and ‘rectangles’ can be realized in crystalline state through weak interactions.12,26,54,61,69,66,91,93 • Anion Receptor Chemistry: Since anions capture is important to deplete them from the solution to a level below the toxicity limit, strategies have been designed to precipitate them completely. The research conducted in this direction can become important in pollution control.16,17,42-44, 46,58,66,67 • Unprecedented Anions: The insight gathered from the second sphere interactions and inorganic crystal engineering has been effectively utilized for the first time isolation and characterization of anions such as [Hg2(SCN)7]3-, [HgBr5]3-, [HgBr4Cl]3-, polymeric [Cd3Br10.2H2O]4-, trans[CdBr4Cl2]4-, [CdBr4Benzoate]3-,[Cd2X7]3- etc. Since these anions are very new to the chemical world, much scope exists for their elaborate studies in a variety of complex salts. 12,14,15,22,29,39,84 He is recipient of several national and international assignments, authored two chapters in books and has collaboration with several foreign research groups.

SRIVASTAVA, AKHILESH KUMAR (b 1974) Lecturer, Department of Chemistry, St. Andrew's College, Gorakhpur - 273001 Member of the NASI: No (YON 2011, Chemical Sciences) Organometallic Chemistry is one of the most important and emerging branch of Chemistry and its applications will continue to benefit society. Although tremendous progress has been already made, the kinds of organometallic compounds so far studied and utilized have still been limited. Many catalytic and non-catalytic stereoselective processes that are key steps in creative and non-conventional synthesis of complex molecules have gained significant advantage from organometallic chemistry i.e. Monsanto's synthesis of L-dopa, Ziegler-Natta catalysts for polymer production, Chiral Noyori's catalysts for hydrogenation and hydrogen transfer, olefin metathesis. Dr. A.K. Srivastava has published several important findings on new routes for synthesis of novel cyclopentadienyl derivatives of Group IV transition metals and their spectroscopic properties. He has also done important work on biochemical aspects of these derivatives. At present, he is mainly involved on synthesis of supra cyciopentadienyl derivatives of Group 4 transition metals and lanthanides. He is also studying the catalytic properties of the synthesized derivatives. At present, Dr. A.K. Srivastava has three major projects sanctioned by CST, U.P. (Young Scientist Project, 2008-2011), UGC (2010-2013) and DRDO, New Delhi (2011-2014). In addition, Dr. Srivastava has been awarded International Research Fund Support by The Royal Society of Chemistry (London) for consecutive two years (2008-09 and 2009-10). He is life member of Indian Science Congress, Indian Chemical Society, Indian Council of Chemists, Indian Society of Analytical Scientists and member of the Royal Society of Chemistry (London).

CHATTOPADHYAY, NITIN (b 1960), Professor, Jadavpur University, Kolkata Member of the NASI: No (YON 2010, Chemical Sciences) Professor Chattopadhyay has made significant and new contributions to modern photophysics/photochemistry and biophysical chemistry which is acclaimed globally. He is a Fellow of the Indian Academy of Sciences (2010) and West Bengal Academy of Science and Technology (2009). He is the recipient of CRSI Bronze Medal (2013). He is an Associate Editor of Journal of Luminescence (2013) and a member of the Editorial Boards of Journal of Colloid & Interface Science (2014), Journal of Photochemistry & Photobiology B: Biology (2012), and Journal of Chemical Sciences (2012). He has developed many simple chemical/molecular strategies that have immense potential for applications in photochemistry, sensing technology and medicinal research. His strategy of introducing micelles has increased the fluoro-sensing efficiency by more than three orders of magnitude. This strategy is powerful enough to enable cationic fluorophores to sense cationic analytes efficiently, reported for the first time. He also developed a simple strategy for detection and estimation of deadly toxic cyanide ion in aqueous medium down to micromolar concentration employing only a spectrophotometer. In another biophysical work, he has demonstrated a remarkable enhancement of the efficacy of an ionic drug by pushing it into the hydrophobic interior region employing salts. This can reduce the dose of the drug, and hence, lower the cost and drug-induced side effects. He has also shown how unused drugs accumulated in the cell membranes can be excreted from the body simply by using cyclodextrins. Exploiting his indigenous strategy he has established emission from the S2 state of 1,2-dicarbonyls.

Dr. Panda has made vital contributions towards the development of potent therapeutic agents in the area of cancer and tuberculosis. During his Ph.D. and post-doc, he worked on design and synthesis of bucky-bowls and heterogeneous catalysts respectively. However, he has independently developed as a medicinal chemist and elegantly utilized his training as an organic chemist to solve problems of biological interest. i) AAs Derived Bioactives as anticancer agents: He has conceived elegant strategy for the synthesis of all isomers of alkaloids bearing multiple asymmetric centers from AAs. His notable contributions include i) first synthesis of all stereoisomers of PKC inhibitor (-)-Balanol and Ophiocordin, ii) stereoselective route to (+)-epiquinamide and (+)-α-conhydrine, C3-epi-(+)-lycoricidine, Jaspine B, 8,8a-diepicastanospermine, (-)-Swainsonine, L-altro-DNJ, levofloxacin and 2-oxopiperazines. In the quest for steroidomimetics, he envisages to employ AAs and its inherent chirality towards chiral heterosteroid architectures and related seco/modified-steroids. Hetero [6-5-6] tricyclics resembling Taiwaniaquinoids and C-nor-D-homo steroids were synthesized through first heteroaromatic Nazarov type cyclization with excellent regioselectivity. His chiral serine azide through Weinreb amide to reduce acidity of α-proton is widely utilized. ii) syn-2, 3-dihydroxy esters for developing molecules as anticancer: His contribution in this field includes i) enantioselective formal total synthesis of all stereoisomers of (─) -Raphidecursinol B ii) first protecting group-free syntheses of spisulosine and its diastereo- and regioisomers. iii) Unsymmetric Trisubstituted methanes (TRSMs) as antitubercular agents: His consistent effort has resulted in bringing TRSMs with high potential towards developing antitubercular agents. One molecule (CDRI; S-006-830) had been taken over by Open Source Drug Discovery (OSDD) for further development as candidate drug.

Prof. B. K. Patel’s group at IIT Guwahati has made significant contribution in the area of Synthetic Organic Chemistry. They have developed metal free and transition metal catalyzed reactions for the construction of CC and Cheteroatom bonds via cleavage of ubiquitous C H bonds following chelation assisted and cross dehydrogenative coupling (CDC) strategies. The various CH bonds that have been functionalized include a range of sp2 and sp3 hydrogens as mutual or cross coupling partners. During activation process tandem reactions leading to the synthesis of bioactive heterocycles has been achieved. His group’s other major achievements in the area of Green Chemistry include the use of non toxic and benign reagents such as H2O2, V2O5, Cu, iodine, hypervalent iodine, and bromine less brominating reagents in lieu of toxic reagents such as thiophosgene, CNBr, KCN, Br2, and heavy metal oxidants. The development of innocuous methods for the synthesis of alkyl and aryl isothiocyanates, cyanamides and carbodiimides from inexpensive and readily available materials such as amines, carbon disulfide and molecular iodine [or hypervalent iodine, organic ammonium tribromides] are noteworthy. These precursors are prepared not only by a one-pot procedure but also have been employed for the construction of heterocycles in one-pot which are sustainable and environmentally acceptable. Investigation of mechanisms of newly designed reactions has augmented fundamental understanding of chemistry. Based on the understanding of reaction mechanisms, it has been possible to correct the incorrect structures published in reputed journals for some of the heterocycles and have accounted for several interesting observations.

PRATAP, RAM (b 1954), Scientist G, Medicinal and Process Chem. Div., Central Drug Research Institute, Lucknow - 226001 Member of the NASI: No (YON 2010, Chemical Sciences) Dr Ram Pratap has keen interest in drug designing for metabolic syndrome with a novel mechanism of action. A product, 16-dehydro-pregnenolone with generic name CENTATIN has completed phase III human trial as lipid lowering. It has unique mechanism of action not known with any other anti-hyperlipidemic drugs. It binds with the farnesoid X receptor (FXR) on hepatic membrane to antagonize the salvage of bile acids and other cholesterol metabolites as a result these metabolites are excreted into faeces. In 2008 September, CDRI received ‘CSIR Technology Award’ for this innovation. He has synthesized another molecule S007-1261 of pregnane class for TGR5 receptor which has significant antidiabetic activity in db/db mice and has been selected for drug development. Another area of he has undertaken is the stimulation of thermogenesis for antidiabetic and antidyslipidemic activity. Stimulation of β3-adrenoceptors by selective agonists improves insulin action and stimulates energy metabolism in various rodent models of obesity and type 2 diabetes. His recent works on flavones and chalcones with β3-adrenoceptor pharmacophore have provided a molecule S002-853 and S001-469. Compound S001-469 is in the process of drug development. He has also worked on anti-metabolite approach to synthesize nucleosides for anti-leishmanial activity. He has prepared nucleosides analogs of purine, pyrazolo[3,4-d] pyrimidine and their isosteres to follow their anti-leishmanial activity. A simple pyrazolo [3, 4-d] pyrimidine nucleoside has been found to inhibit amastigotes proliferation by ~ 95% in hamsters. During nucleoside work, he isolated an unusual oxetane compound which was found to have potent antiviral activity in vivo.

RAWAT, DIWAN S. (b 1970), Professor, Department of Chemistry, University of Delhi, Delhi Member of the NASI: Yes (YON 2010, Chemical Sciences) Over the last sixteen years Professor Rawat has made significant contribution in the fields of medicinal chemistry and drug discovery programme. In this direction his focus has been to develop novel organic molecules for the treatment of deadly diseases such as cancer, malaria and microbial infections. He has made original contribution in the area of enediyne chemistry (J. Am. Chem. Soc; Chem. Commun; Inorg. Chem.), farnesyl transferase based FTase inhibitors (Org. Letts.; ACS Chemical Biology; J. Org. Chem.). The work on enediyne opened new directions for the development of enediyne based anticancer molecules, wherein it was discovered that judicious choice of metal can improve the anticancer activity of the enediynes. He has made seminal contribution in the area of antimalarial research and developed small organic molecules for the treatment of malaria (Med. Res. Rev.) and bacterial infections (Med. Res. Rev.); Org. Biomol. Chem.; FEBS Journal,; Chem. Biol. Drug Des.; ACS J. Agric. Food Chem.). Some of compounds based on 4-aminoquinoline-pyrimidine pharmacophore have shown excellent in vitro and in vivo antimalarial activity without any toxicity (ACS Med Chem Lett,; RSC Adv.) and these compounds have also shown anti-Parkinson activity (PCT 2013). More recently, his work on curcumin derivatives led to the discovery of novel anticancer agents which is much better than doxorubicin (US Patent, 2012; Med. Chem. Commun,). His work on catalysis led the discovery of novel heterogenous materials as a recyclable catalyst for the synthesis of biologically relevant heterocycles (Adv. Synth. Catal.; RSC Adv; Green Chemistry).

Chemical Division, National Centre for Mass Spectrometry, Indian Institute of Chemical Technology, Uppal Road, Tarnaka, Hyderabad - 500607 Memberofthe NASI: No (YON 2010, Chemical Sciences) Dr. MVairamani's research interests are in studying ion molecular reactions in the gas phase using mass spectrometric techniques such as chemical ionization, fast atom bombardment, and electrospray ionization. He developed many new chemical ionization reagents such as acetone, nitromethane, 1,2-dibromoethane, and ethylene glycol for differentiation of isomeric compounds. He showed that naturally occurring sugars can be used as chiral matrices to differentiate chiral amino acids and amines under fast atom bombardment. He has measured the proton affinities of three isomeric hexosamines, N acetylhexosamines and some hexoses for the first time using the kinetic method. He studied the formation of Guanine quadruplex by the Thrombin Binding Aptamer under electrospray ionization mass spectrometry. His collaboration work with NGRI scientists resulted in finding fullerenes in low grade metamorphosed Proterozoic shungite from Karelia, Russia and in the Cretaceous-Tertiary boundary layer at Anjar, Kutch, India which is a significant contribution towards the formation of fullerenes in nature. Recently he showed for the first time that DNA triplet GCA can be used as a chiral auxilliary for the discrimination of enantiomeric amino acids. He also developed diiodo tyrosine as a good chiral auxiliary for chiral determination of aliphatic amino acids. He established the Centre for the Analysis of Chemical Toxins at IICT, Hyderabad with International designation status for the off-site analysis of residual chemical weapon related chemicals with a view to assist Government of India for the implementation of Chemical Weapons Convention and it is one of the 18 such laboratories in the world to-day.

BAKSHI, GURMEET KAUR (b 1970), Professor, Centre for Advanced Study in Mathematics, Panjab University, Chandigarh, India
Member of the NASI: Yes (YON 2014, Mathematical Sciences)
Gurmeet K. Bakshi has made significant contributions in Group Rings and Algebraic Coding Theory. Bass[1976] conjectured that if R is a subring of the ring of complex numbers which when intersected with rationals is the ring of integers, G an arbitrary group and E in Mn(R[G]) an idempotent matrix over the group ring R[G] of G over R, then the partial augmentation of the trace of E corresponding to any non identity conjugacy class of G is zero. Bakshi[1994], in a joint work, has contributed to the conjecture by providing new groups that satisfy the conjecture. In [1998], its impact on torsion units in integral matrix group rings was studied. Bakshi, in joint works, has obtained many results on irreducible cyclic codes, Polyadic codes and constacyclic codes. During [2002-08], she has obtained the generating idempotents of irreducible cyclic codes. In [2007] and [2012], the weight distribution was given. During [2007-08], she studied Polyadic codes and gave examples of some good codes. Classification of certain constacyclic codes and negacyclic codes was given in [2012-13]. Contributing to the structure of group algebras, a complete set of primitive central idempotents of the rational group algebra of interesting family of groups was obtained in [2012]. In a joint work, she obtained the complete structure of the rational group algebra of a metabelian group [2013] and finite metacyclic group algebras [2012-13]. Recently, she has obtained the structure of the rational group algebra of a normally monomial groups.

Gandhi approached me for the Multidisciplinary guidance of SO MA S S (www.somass.org) during 2004 while he was studying M.Sc. (Math). He came out with first class in M.Sc.(Math), M.A.(Ed) & M.Phil (Math). He got his PhD and he is actively guiding research. From 2009, he was discussing with me his difficulties in research in Theory of numbers. I found his intuition to be of high order and helped to develop other components of intellect (well ordered intelligence) like critical faculty, communication and well sorted memory. Our discussion resulted in the publication of two papers of an interdisciplinary nature. The discussions also gave him the competence and opportunities to publish and keep on publishing several other papers and others like invited monographs (enclosed to his C.V.). Prof. Gandhi has a natural zeal to consult various books and carryout teaching in addition to research. I strongly believe that, he is most suitable and eligible to have our esteemed Fellowship.

LAHIRI, INDRAJIT (b 1961), Professor, Department of Mathematics, University of Kalyani, WB Member of the NASI: Yes (YON 2014, Mathematical Sciences) In the area of value distribution theory Prof. Indrajit Lahiri’s idea of gradation of sharing of complex values has been acclaimed internationally which is known in the literature as weighted sharing of values. This concept enables various international workers to derive several theories under much weaker hypotheses. Using this idea Lahiri etal. answered open questions posed by K. Tohge. Mues’ conjecture related to meromorphic functions remained unsolved for a long time. Prof. Lahiri found a possible solution to the conjecture after proving the validity of the conjecture for meromorphic functions having no simple a-points for some finite complex number a. Prof. Lahiri with Dr. Kit Wing Yu obtained a partial answer to a question raised by Prof. W. K. Hayman on generalized Fermat type functional equations. The Bloch principle and its converse drew attention of distinguished workers during the last three decades. Prof. Lahiri augmented the theory by adding another counter example to the general converse of Bloch principle. Following Lahiri’s method, K. S. Charak and J. Rieppo added one more counter example to the general converse of Bloch Principle. Also other authors like J. Xu and W. Cao, X. B. Zhang, J. F. Xu and H. X. Yi, J. Yunbo and G. Zongsheng used Lahiri’s technique to derive normality criteria for families of meromorphic functions and to add more counter examples to the converse of Bloch Principle. Total number of citations of Lahiri’s work is 925 and his h-index is 16 as available in Google scholar.

SINGH, TEJ BAHADUR (b 1952), Professor, Department of Mathematics, University of Delhi, Delhi-110007. Member of the NASI: No (YON 2014, Mathematical Sciences) For a space X with a periodic homeomorphism of prime period, Smith [1937] introduced the study of homological relationships among the space X, the fixed point set and the orbit space. Dr. Singh (jointly with Dotzel) has given a complete description of possible fixed point sets of periodic maps of prime period on spaces of cohomology type of P2(n)VS3n (here P2(n) is a projective plane and S3n is a sphere of dimension 3n) or the wedge nVS2nVS3n. The possibility of existence of a fixed-point free homeomorphism on these spaces has also been observed and, in this case, the (modp) cohomology structure of the orbit spaces has been determined [3,4]. Similar results for periodic maps of odd prime order on product of two spheres and generalized lens spaces has been proved [5,6]. The above results classify the cohomology type of spaces with the fundamental group Zp and the covering space of cohomology type of SnVS2nVS3n, n 1, or Sm×Sn, both m,n 1, or the complex projective space CPn (p=2 in this case) [4,5,7]. These results have helped to prove Borsuk-Ulam type theorems: Non-existence of equivariant maps Sm → X relative to the antipodal action on Sm, where X = RPn, CPn and SnVS2nVS3n (n 1). Similar results for the actions of the circle group on spaces of cohomology type of SnVS2nVS3n or S1×CPm-1 have been obtained 8,9].

SURY, BALASUBRAMANIAN (b 1960), Professor, Indian Statistical Institute, Bangalore Member of the NASI: No (YON 2014, Mathematical Sciences)
Prof. B. Sury has made significant contributions to the following areas of mathematics: (a) algebraic groups, (b) number theory (c) group theory. In algebraic groups Sury has made extensive contributions to the congruence subgroup problem. Along with Mason et al., Sury has conmpletely determined the congruence kernel of arithmetic lattices in algebraic groups over local fields under mild hypotheses on the group. Sury established a result concerning abstract central extensions of G(k) where k is a local non-archimedean field by an abelian p-adic group where p is the characteristic of the residue field of k. (This is an analogue of a result of Gopal Prasad and M S Raghunathan concerning topological central extensions.) In group theory, he has obtained many interesting results. A major and surprising result is that a finitely generated group of bounded generation is not necessarily finitely presented. With Evorenko, Sury has computed the asymptotic commutativity degree of group which is a wreath product of two abelian groups. Sury computes the number of p-Sylow subgroups of a wreath product of two finite groups (under some natural hypotheses.) In number theory, Sury made several noteworthy contributions to arithmetic, particularly to Diophatine problems. In a series of papers he studies sums of terms involving reciprocals of the binomial coefficients. Sury has obtained an asymptotic formula for the number of primes which divide sum k-th powers two fixed positive numbers. In a follow up, (jointly with P Moree) a formula for the densities of primes satisfying certain congruence relations are obtained.

Kotzig, Dr. Vijayakumar noted that the counter example provide had a fallacy, and then he provided a class of graphs -strongly vertex triangle regular self-complementary graphs – which are counter examples. The results obtained to reach this conclusion were quite significant from which the results of Lorden, Clapham, Rao and Cameron could be deduced. In the area of Graph energy he constructed equi-energetic graphs and computed the energies of non-regular graphs from that of regular ones. Introducing the concept of ‘distance energy’ and obtaining bounds for the same were also reasonably significant. Based on a problem posed by Erdos et. al, the notion of - property could also be studied. Another contribution of the nominee is to the dissemination of knowledge. He has written popular articles mostly in Malayalam language on various aspects of mathematics such as social networks, cryptography, fractals,Ramanujan’s works etc. through leading newspapers .He has published more than fifty such articles. He has also been a MENTOR of the INSPIRE program of DST since many years. He is the founder Academic Secretary of Kerala Mathematics Teachers Association (KMTA) - a forum for school mathematics teachers , since 2001 . He is also associated with many science education /research programs of the Government of Kerala and is also working for the educational uplifting of socially and economically backward students.

GANAPATHY, GANESAN (b 1968), Professor, Department of Mathematics, Adikavi Nannaya University, Rajahmundry, Andhra Pradesh Member of the NASI: No (YON 2013, Mathematical Sciences) Dr.G.Ganesan’s work on deriving rough fuzzy predicates has a considerable impact in the field of fuzzy logic by extending it into rough fuzzy logic. Also, his work on the algebraic structure namely rough fuzzy groups define a new way of clustering in any information systems through which the arithmetical operations can be performed in between the clusters of the records. This approach leads a naïve way of defining security keys using the clusters within the information system which helps to improve the immunity against any attacks. Further, he has derived a naive fuzzy bags structure to approximate the given granule under fuzzy environment which leads various applications in machine learning. Also, he derived a mechanism of reducing the ambiguous region in rough computing which helps the computer scientists to approximate the given concept with more accuracy. He has been the Editorial Board member for various reputed journals and has been associated with more than a hundred conferences held/being held/ to be held in various countries. Considering the significant work of Dr.G.Ganesan in the area of Soft Computing, Government of Andhra Pradesh awarded Scientist Award-2012 in the field of Mathematical Science. Also, Bose Science Society awarded him Srinivasa Ramanujan Best Mathematician Award (2012-13). Further, he has a lot of awards and appreciations on his crown.

GANGAVAMSAM, RAJA SEKHAR PYDI (b 1970), Professor, IIT Kharagpur, Kharagpur Member of the NASI: Yes (YON 2013, Mathematical Sciences) The nominee works in the area of Fluid Mechanics and in particular Low Reynolds number flows and flow through porous media. Some of the major contributions are (i) Results on the completeness of a general solution for Stokes/Brinkman equations in terms harmonic, biharmonic and Helmholtz scalars. This solution has been proven to be very efficient in dealing with arbitrary Stokes flows for spherical geometries. (ii) For the first time in literature, Green’s function corresponding to Brinkman equation in a 2D case of hydrodynamic anisotropy with respect to the permeability has been derived. (iii) Hydrodynamic problems of steady flow of a viscous incompressible fluid involving porous bodies of arbitrary shape whose boundary is a closed Lyapunov / Lipschitz curve have been dealt in terms of boundary integral formulations. The existence and uniqueness results for a three-dimension Stokes-Brinkman cell model and for a two-dimensional low Reynolds number flow past a porous body in some Sobolev or Holder spaces contain rich mathematical theory. (iv) Rigorous estimates for the 2D Oseen–Brinkman transmission problem in terms of the Stokes–Brinkman expansion are notable ones in this direction. (v) Some of the studies close to application areas are on viscous flow past a deformed void in a porous media as an application of measuring the velocity of groundwater; convection diffusion reaction inside porous pellets subject to various boundary conditions as an application to bioreactors; estimating the overall bed permeability of bed of porous particles. Recent work is on Thermocapillary dift on a viscous drop.

RAMANA, DEVARAKONDA SURYA (b 1969), Associate Professor, Harishchandra Research Institute, Chhatnag Road, Jhunsi, Allahabad - 211019 Member of the NASI: No (YON 2013, Mathematical Sciences) Dr Ramana has carried out three outstanding pieces of work which deserve recognition. A classical theorem of Vinogradov asserts that every sufficiently large integer can be expressed as the sum of no more than 4 prime numbers. Dr. Ramana addresses the following question. If a sequence of primes is coloured with K colours,K an integer which is at least 1,then what is the least number t(K),such that every sufficiently large integer is the sum of no more than t(K) primes,all of the same colour. The answer found (paper # 1) is t(K) = C K ln(ln4K)and this is optimal upto the value of the constant C. Number of rationals represented as ratio of 2 integers,one from the interval [1,N],the other from [1,M] is asymptotically like MN.The nominee considers the number of rationals representable as ratios of large but otherwise arbitrary subsets of these intervals.Remarkably it is shown that large sets,in this context, behave like intervals.This helps answer an issue concerning gaps between terms of the product sequence of two dense subsequences of integers ( paper 2) Points with integer coordinates lying on a curve in the plane "tend to repel each other".Similar phenomena occur with divisors of integers all belonging to certain arithmetical progression.Dr Ramana has given a simple identity that allows easy recovery of the best known results in this area. This work has drawn attention of extremely prominent mathematicians like Bourgain and Rudnick.

ROY, RAHUL (b 1959), Professor, Theoretical Statistical and Mathematics Unit, Indian Statistical Institute, JSJS Sansanwal Marg, New Delhi - 110016 Member of the NASI: No (YON 2013, Mathematical Sciences) Rahul Roy has made significant contributions with substantial impact in the fields of continuum percolation, stochastic geometry and random graphs. Besides these three areas he has also made contributions and supervised students in the area of bio-informatics. Rahul has written several popular articles on the history of mathematics. In his early work in the field of continuum percolation he established the sharp phase transition in 2-dimensional Poisson Boolean models. He also showed the uniqueness of the infinite cluster in a wide range of stationary Boolean models. Besides he disproved a conjecture of physicists regarding the covered volume fraction in continuum percolation. These and other results are summarized in the research monograph (written jointly with Ronald Meester) Continuum Percolation (Cambridge Univ. Press 1996, reprinted in paperback 2008). This book has been cited extensively not only by mathematicians, but also by physicists and researchers in wireless communication. In recent years, he has been studying random graphs as well as coverage questions of the integer lattice. On random graphs he has studied drainage models arising in physics. An open vertex is connected to the `nearest’ open vertex in a particular direction. Here Rahul has shown a dichotomy in the geometric structure vis-à-vis dimensions. He has also shown that, in 2-dimensions, under suitable scaling the graph converges to a Brownian web. Rahul has been working with his younger colleagues from the three centres of the Indian Statistical Institute and over the years has developed a school of active probabilists working on the questions of particle systems, percolation and random graphs.

DATTA, BASUDEB (b 1957), Professor, Indian Institute of Science, Bangalore Member of the NASI: No (YON 2012, Mathematical Sciences)
One of the earliest work of Professor Datta in Differential Geometry is determination of manifolds of the form S2p×S2q which admit almost complex structures. A remarkable contribution of Datta in Combinatorial Geometry is the determination of all convex n-gons of a given diameter which maximize perimeter. His other works are mostly in Combinatorics and Combinatorial Topology. One of his most influential work is the first theoretical proof of existence and uniqueness of Kühnel's remarkable 9-vertex complex projective plane. In a later work, he found a remarkably short and elegant proof of this result. A widely quoted work is a structure theorem for pseudomanifolds, leading to a complete determination of all d-dimensional pseudomanifolds on ≤ d+4 vertices for all d. Datta proved that any triangulation of a non-simply connected closed manifold of dimension d ≥ 3 requires at least 2d+3 vertices, and there is a unique such triangulation on 2d+3 vertices, triangulating an sphere-bundle over circle. Its proof is a beautiful mix of topological, geometric and combinatorial arguments. He has constructed a 30-vertex triangulation of CP3. It is the first explicit construction of a triangulation of CP3. Recently, he has constructed an infinite series of tight triangulated manifolds. This is the first series of examples of such manifolds after 26. Perhaps Datta's best work is his recent paper in EJC, in which he obtained a very general combinatorial criterion for tightness of closed triangulated manifolds.

DEKA, RUDRA KANTA (b 1961), Professor, Department of Mathematics, Gauhati University, Guwahati-781014 Member of the NASI: No (YON 2012, Mathematical Sciences) Professor Rudra Kanta Deka has made substantial and fundamental contributions in the research work pertained to flow past plates and cylinders, flow past porous media, heat and mass transfer with thermal stratification (vertical advection) including stability of flows (Taylor-Couette flow, Dean flow and Taylor-Dean flow) with radial heating. His analysis on the hydrodynamic instability of flow between permeable circular cylinders driven by a constant azimuthal pressure gradient reveals that a positive throughflow has a stabilizing effect on the flow. This result has important bearing on Keplerian astrophysical disks and this work has been abstracted in ‘Solid State and Superconductivity’. While studying the stability of the Taylor-Dean flow with radial heating, he found that the radial heating leads to a complete stable flow. He has applied wavelet Galerkin technique to solve partial differential equations and established the reliability and accuracy of the differential transform method in the analyses of instabilities of circular Couette flows between circular cylinders. He has published 101 research papers, guided 15 PhD students.

GUPTA, VIJAY (b 1962), Professor (Mathematics), School of Applied Sciences, Netaji Subhas Institute of Technology, New Delhi – 110078 Member of the NASI: No (YON 2012, Mathematical Sciences) Professor Vijay Gupta has made excellent contributions to the area of Approximation Theory, especially on Linear Positive Operators through his sustained research works [1]-[231], which have been published in journals of international repute. Recently, he has written a book on`Applications of q-Calculus in Operator Theory for Springer, US which will be released in April 2013. His most significant contributions are: • He first ever introduced several integral type operators so as to approximate Lebesgue integrable functions on the real axis [17], [24], [29], [65], [78], [80], [90]. He established the technique to discuss inverse results for integral type operators [10], [38], [156]. • He estimated first time the rate of convergence for functions of bounded variation and for functions with derivatives of bounded variation of several summation-integral type operators. He also introduced the Bezier variants of many well-known operators and established rate of convergence [47], [58], [66], [68], [69], [76], [78], [95], [101], [103], [111], [122], [128], [145]. • First time he introduced the q-analogue of well-known operators and established approximation properties [94], [113], [10], [148], [163], [170], [180], [185], [191], [195], [207], [210]. • Very recently he worked jointly with Prof Gal and estimated first time the exact quantitative estimates for Durrmeyer-type operators and its q analogue in complex domain [192], [193], [204], [206], [212]. Professor Gupta, by most of his research work carried out exclusively in India, has made significant impact on the area of Approximation Theory nationally and internationally.

In control theory, one of the most important qualitative aspects of a dynamical system is controllability. This has been extensively studied for finite dimensional linear systems. Dr.Balachandran has investigated the controllability problem for different classes of nonlinear systems. He introduced the concept of asymptotic null controllability for dynamical systems. Dr.Balachandran studied the controllability problem for various kinds of abstract functional integrodifferential systems, stochastic systems, fractional dynamical systems and partial differential equations. In control theory alone he has published more than 100 papers in SCI journals. This is the single most achievement of Dr.Balachandran. Indeed it is a commendable work. Apart from control theory, he investigated the existence problem for various classes of differential and integral equations. The results have been established with the help of fixed point principles. In differential equations, he has published over 50 papers in SCI journals. As per Scopus, Dr.Balachandran has nearly 217 papers and 1390 citations and his h-index is 17. His two survey papers on controllability of nonlinear systems have the citation of 120. As per Google Scholar, Dr.Balachandran's publication is more than 330 and the citation is 3424 and h-index is 28. His publication list in MathSciNet is 322. In fact, Dr.Balachandran's contributions to the fields of control theory and differential equations are highly commendable. Dr.Balachandran's most significant contribution is the successful application of fixed point technique to control theory and differential equations. For these contributions, I strongly recommend him for the Fellow of National Academy of Sciences, India.

PRABHALA, MURTHY VENKATA SATYANARAYANA (b 1970), PROFESSOR, DEPARTMENT OF MATHEMATICS, INDIAN INSTITUTE OF TECHNOLOGY KHARAGPUR Member of the NASI: No (YON 2012, Mathematical Sciences) His research focus is on the magnetic drug targeting in micro blood vessels with non-Newtonian blood models which involves finding the trajectories of the drug dosed magnetic carrier particle in a micro vessel which is subjected to the external magnetic field. This is one of the active research areas in the bio-fluid mechanics which has applications in treating tumors in various parts of the human body. In human blood vessel, the endothelium cells are covered with a gel-like layer of membrane-bound glycol-proteins and plasma proteins, named as the glycocalyx layer which is a porous layer. The carrier particles, bound with nanoparticles and drug molecules are injected into the vascular system upstream trom malignant tissue, and captured at the tumor site using a local applied magnetic field. The applied magnetic field is produced by a cylindrical magnet positioned outside the body and near the tumor position. To capture the particle at the tumor location, the fluidic force experienced by the carrier particle traversing in the two-phase fluid in the micro vessel has to be countered by the magnetic force due to the external magnetic field. Several factors that influence the magnetic targeting are the size and shape of the carrier particle, the volume traction of embedded magnetic nanoparticles, and the distance of separation of the magnet trom the axis of the micro vessel. A prediction of the capture of therapeutic magnetic nanoparticle in the impermeable microvasculature is made for different radii, distances of separation and volume tractions in both the invasive and noninvasive cases.

Dr. Ramajayam Sahadevan has made seminal contributions to the field of Integrable Systems, a challenging area in the theory of nonlinear differential equations. Dr. Sahadevan’s multifaceted investigations have enriched the subject and made profound impact in the field and opened up new avenues for further research. His seminal contributions have received much attention, are well cited and have enhanced the image of integrable systems research in India at international fora. Recently he has made fundamental contributions in discrete integrable systems by developing an analytic method to find discrete version of integrable ordinary and partial differential equations preserving the characteristics of the original equation which is one of the striking results in this area. Dr.Sahadevan has discovered a family of 4th order symplectic and integrable nonlinear difference equations which has generated a lot of interest now in the field. In a related development he has identified higher dimensional discrete Painleve transcendental equations. Dr.Sahadevan has introduced a novel analytical method to derive conservation laws for nonlinear partial difference equations and remarkably shown that certain methods of integrability are equivalent. Dr.Sahadevan has also reported several 3 and 4 dimensional integrable mappings. Dr. Sahadevan and his collaborators have demonstrated how the Lie Backlund transformation group theory to derive important algebraic structures related with complete integrability of discrete soliton equations can be developed. Dr. Sahadevan’s analysis on the singularity structure of solutions in the complex plane/manifold of nonlinear differential equations has helped to discover several new integrable systems of high mathematical and physical relevance.

Dr Saravanan works on partial differential equations and scientific computing applicable to real world problems. He has made significant contributions to theoretical and computational fluid dynamics by finding results of fundamental importance in heat convection theory. He has used different mathematical techniques to predict a variety of convective flows and their stability. He has modelled convective instabilities driven by spatially nonuniform heat sources found in photochemical reactions for the first time in the literature to my knowledge. Based on a higher order spectral collocation method, a unique approach of its kind, he has identified thermal buoyant, shear and interactive modes of convective instabilities. He has extensively dealt with resonances of dynamic instability corresponding to time dependent equilibrium states. In such systems he has established the existence of closed disconnected instability regions. His use of nonlinear stability theory, through energy inequalities and variational principles, in describing centrifugal convection has been well accepted globally. Prof. Straughan and his co-workers have highly commended his work (Int. J. Engng. Sci., 48 (2010) 1610–1621 and Nonlin. Anal.: Real World Appl., 12 (2011) 2839-2843). He has investigated convection occurring in enclosures with particular references to nuclear reactor safety and electronic equipment cooling. He has published results in highly respected journals like Proc. Royal Society A, Physics of Fluids, Physical Review E, etc. He has received Young Scientist Awards from ISTAM (2000), lSCA (2003) and IMS (2007). He was a CSIR NET Junior/Senior Research Fellow (1997-2001), JSPS Fellow (Japan-2004-05) and BOYSCAST Fellow (Germany-2010).

SRIVASTAVA, PARMESHWARY DAYAL (b 1953), Professor & Head, Department of Mathematics, Indian Institute of Technology, Kharagpur - 721302 Member of the NASI: Yes (YON 2012, Mathematical Sciences) The candidate’s work is mainly motivated by the development of the theory of sequence and function spaces over the past few decades in one direction and Security weaknesses of protocols for digital signatures, smart-card authentication and access control in other direction. The present day theory of sequence spaces is no more limited to the summability theory alone but has gone much beyond with the applications of functional analysis and structural theory of topological vector spaces. An attempt is made by the candidate to study the theory of sequence spaces with regard to some recent aspects like the scalar & vector - valued sequences, Orlicz & Modulus functions, duality theory, statistical convergence, Spectrum of difference operatos etc. In fact, a generalized vector - valued sequence space F (Ek, Λ) is defined as a sort of unification and generalization of several known scalar and vector valued sequence spaces. This is done by combining a sequence space F, a sequence of Banach spaces Ek, k= 1,2 ---- and a multiplier sequence V= (Vk). A suitable topology is defined on this space with the help of the topology of F and those of Ek, k=1,2... It is established that F (Ek, Λ) is a complete paranormed space under this topology. Various aspects such as -and continuous duals, convergence, separability, the aspects like weak and weak* - convergence, sequential completeness, compactness, characterization of matrix transformations etc. are studied. In continuation, an attempt is also made to study the various algebraic and topological aspects for composite vector valued sequence spaces F (Ek, f), F (Ek, M), F (X, r), F (X, ,f);

Further, the study of proper basis in a complete linear metric spaces is also made which unifies many known results by earlier workers such as Iyer [1948],Arsove [1957],Krisnamurthy [1960] and others. Several known function and sequence spaces studied by Lalitha [1969], Kothe [1969], Leonard [1976],

GAKKHAR, Sunita (b. 1955) Professor, Deptt. of Mathematics, Indian Institute of Technology, Roorkee - 247667 Member of the NASI : Yes (YON 2011, Mathematical Sciences) Prof. Sunita Gakkhar has significantly contributed to the interdisciplinary area of Mathematical Ecology, where the underlying dynamical system consists of multi-dimensional nonlinear coupled ODE’s. In particular, Prof. Gakkhar has studied global dynamics for food chains and food webs. Suitable combination of Bifurcation diagrams, Poincare sections, Liapunov exponents etc are used for identifying the presence of complexity in dynamical behavior. Software has been developed for the simulation. Her work in this direction has been a trend setter and many investigators are now using similar tools in ecological and epidemiological systems. Various ecological phenomena may not be instantaneous and subjected to seasonal variations leading to non-autonomous models. Very few results are available when multiple delays and seasonal variations are considered. Prof. Gakkhar has successfully tackled mathematical intricacies in such models. She has also studied some impulsive systems applicable to impulsive harvesting and pulse vaccination. These are helpful in developing sustainable harvesting policies and successful vaccination strategies. She has also contributed to mathematical Eco-epidemiology to understand the dynamics of diseases transmission. She has made contributions in Bioinformatics also. A web server is developed to compute Higher Order Residue Interactions in protein structures. Dynamical models have been developed and analyzed to predict the impact of cross talk and feed back in ERK and JNK protein cascades. The cross-talks and feedbacks are found to be responsible for activation of ERK5 in transient manner in the absence of input signals. The mathematical analysis of such networks is a challenging problem.

Main contributions are 1. Obtained an explicit formula for the solution of convex conservation laws with initial boundary value problem and settled an open question of Lax in [2,3] 2. In [5] Obtained a solution for a viscosity solution for autonomous HJ equations when the monotonicity condition violates 3. For conservation laws with flux has discontinuity in space variable,finding a physically relevant solution was a big open problem. A new concept of “Interface/boundary entropy condition” is introduced and explicit formula for the solution was constructed and shown that solution forms an L1 contraction semi group [4]. Godunov type numerical scheme was derived for the discontinuous flux case and showed the convergence of the scheme and a simple explicit formula for the flux is given [6]. Referee says “ I have coded this scheme on a problem that I am familiar with and can verify that ....results in efficient manner”. To understand Existing of under compressive waves, infinitely many (A,B) connection, interface entropy conditions are introduced and shown solution forms a L1 contractive semi group in [7]. In the discontinuous flux case it is shown that BV estimates blows up if and only if connection (A,B) defined is a critical point. This was an unsettled question for a long time and settled in [10] .

Mazumder’s significant contributions are the following: 1) Turbulent flow characteristics and bed form dynamics under flood and tidal flow conditions are studied. The results are evaluated in terms of turbulence statistics and coherent structures in the perturbed flow regions affected by waveform structures oriented against the flow. Secondary points of flow separation at the shear layer over series of dunes are discovered, the well known primary separation points being at the crests; and their influences on bank erosion are evaluated. 2) Theoretical models of sediment suspension, deposition, and size distributions in both are developed using Markovian diffusion process to estimate palaeo-flow conditions and sedimentation in modern streams. 3) A method of moments is developed to solve the unsteady convective-diffusion equation. Novelty of the method is to compute mean concentration distribution and dispersion coefficients in oscillatory flow situations, such as tidal rivers, estuaries with dead zones, and catheterized artery with reversible and irreversible reactions. Method of homogenization is used to solve transport equation in unsteady flows with nonlinear chemical reaction. 4) Transport of sand particles at near-bed turbulence using digital imaging. Theoretical model is developed to estimate thickness of saltation layer of particles. Digital imaging technique is used for better modeling of suspended particles in environments. 5) Turbulence in natural rivers and its effects on the ecology of biologically sensitive areas, which is extremely important to the study of sediment suspension, bank erosion and aquatic habitats. 6) Substantial contributions to the field of MHD flow and heat transfer.

Member of the NASI: No (YON 2011, Mathematical Sciences)
The nominee has been working in the area of mathematical modelling of environmental and ecological systems and mathematical epidemiology including HIV/AIDS. He has developed several new mathematical models to emphasize the importance of precipitation scavenging, with reference to industrial cities, in order to keep environment pollution free. This has led to a new area of research of nonlinear modeling of air pollutants (gaseous and particulates) interaction with rain droplets/cloud drops. The studies conducted are useful to understand the dynamics of nonlinear phenomenon of interactions of pollutants with raindrops which in turn may suggest methods for cloud seeding leading to artificial rain. The analysis may also be useful to understand the mechanism by which toxic gases leaked out in the atmosphere due to accidental discharge, etc. can be removed by introducing suitable liquid or gaseous phase in the environment using mechanical means. His contribution to the field of mathematical epidemiology especially that of spread of carrier dependent infectious diseases, tuberculosis and HIV/AIDS is quite significant in view of the degraded environmental conditions. Moreover, in view of variable demographic structure of Indian society and its vulnerability, such models are very much suitable to understand the spread of HIV/AIDS in Indian context. The studies with regard to screening of unaware HIV infectives, infective immigrants, vaccination thresholds, risky sexual behavior, role of tuberculosis on the spread of HIV infection and subsequent control measures are of paramount importance to contain the spread of HIV infection especially in developing countries.

SHALABH (b 1969), Associate Professor, Department of Mathematics & Statistics, Indian Institute of Technology Kanpur, Kanpur - 208016 Member of the NASI: Yes (YON 2011, Mathematical Sciences) Our nomination is based on the theoretical and applied contributions of Dr. Shalabh in the area of Statistics and his achievements in research, fellowships and awards. He is a well trained Statistician who has worked in a variety of areas in Statistics and is well recognized in the academic community. He has three books (all published from Springer) in his credit which are authored and edited with eminent statisticians like Professors C.R. Rao and H. Toutenburg. He has given a new direction of research by combining the areas of measurement error modeling and restricted regression analysis. His contribution in Statistics has motivated several Indian students and researchers who completed their Ph.D. degrees and produced several research papers. In particular, Dr. Shalabh evolved a framework to analyze the performance of predictors when they are used for the simultaneous prediction of actual and average values of response variables in linear regression model. He has developed several methodologies for the consistent estimation of regression parameters in measurement error models and with restrictions under various nonstandard statistical conditions. He has also suggested an approach for solving the controversies over the use of direct and reverse regression techniques for the calibration of instruments. His contribution in combining the areas of sampling theory and measurement errors is still considered as fundamental. He is probably one among very few Indians who has established himself as an authority in the area of measurement errors.

SINGH, ARINDAMA (b 1964), Professor, Deptt. of Mathematics, IIT Madras, Chennai - 600036 Member of the NASI: No (YON 2011, Mathematical Sciences) Due to the presence of boundary layers, singular perturbation problems are highly sensitive to numerical approximations. Arindama, for the first time, introduced partial decoupling of slow and fast variables in a singularly perturbed system. The decoupled systems could then be solved using simple methods like Euler's and trapezoidal method. For the first time, he used regularization techniques in solving singularly perturbed PDEs. He demonstrated the convergence of regularized solutions using the Tikhonov, Lavrentiev and Showalter regularization. He considered a computationally intractable problem such as knowledge compilation. He developed essentially two different approaches introducing the notion of transversal clauses. He demonstrated that the techniques work in first order logic also. His book on Mathematical Logic, the first book published in India on the subject, has established itself as a well referred text book on Logic. His book on Theory of Computation has become a text book at many universities of repute in a short span of three years. This book, originally published by Springer in English, has been translated to Chinese due to its demand as a text book in China. Recently his research have been directed towards applications such as Learning theory and Image processing. In Learning Theory, his main contributions are theoretical in nature, such as proving consistency of Lavrentiev's regularization method with respect to certain class of Loss functions. In Image Processing, he focussed on denoising and restorations of images. He is also a regular teacher in MTTS camps.

BHATNAGAR, SHALABH (b 1968), Professor, Indian Institute of Science, Bangalore Member of the NASI: No (YON 2010, Mathematical Sciences) The nominee has made stellar contributions in Stochastic Optimization. His work has significantly contributed in making simultaneous perturbation (SP) methods an important area in this field. The nominee has developed several efficient SP estimators for gradient and Hessian of any objective, invented new and more efficient algorithms than what were previously known, and developed for the first time, novel SP methods for constrained optimization, discrete optimization, and reinforcement learning (RL). His one-simulation SPSA algorithm with Hadamard matrix perturbations is the best known one-simulation algorithm for high-dimensional settings. Its perturbation space has the same cardinality as parameter dimension, unlike regular SPSA where this is exponential of it. Further, the nominee has settled three important and long-standing open problems in RL by developing and proving convergence of the first temporal-difference-learning algorithms for nonlinear function-approximators and off-policy prediction and control. Whereas TD diverges under these settings, his algorithms are proved to converge. His work has triggered new worldwide research in stochastic optimization. Because of their good performance, low space requirements and provable convergence guarantees, his algorithms have been significantly applied in various engineering disciplines including vehicular and wireless networks, manufacturing systems, and data mining. One book exclusively based on the nominee's contributions, and which is the only book in this area, has been published by Springer. The nominee has published nearly 120 papers in top-tier journals and conferences and received Fellowships of INAE and IETE; Senior Associateship of ICTP, Italy; Young Scientist award (SSI) and two MSR India Outstanding Young Faculty Awards.

MALASHETTY, MALLESHA SHANKARAPPA (b. 1953) Professor, Department of PG Studies and Research in Mathematics, Jnana Ganga, Gulbarga University, Gulbarga - 585106. Member of the NASI: No (YON 2010, Mathematical Sciences) Dr. M.S: Malashetty has worked on different areas of fluid dynamics especially buoyancy induced flows in fluid and porous media. To date he has 63 refereed journal publications, 9 conference papers and he has also edited two conference proceedings. He is the recipient of the World Canadian Education Foundation "Chandna Mathematics Award" for outstanding contribution in research and teaching in Mathematics in India. He was awarded the "Best Research Publication Award" by the Government of Karnataka, Science and Technology Academy in 2009. He has worked on various academic and administrative bodies. Dr. Malashetty has worked extensively on the problems related to the effect of thermal/gravity modulation on the onset of convection in fluid and porous medium systems. It has been shown in these works that the thermal convection can be effectively controlled by either thermal or gravitational modulation. These problems have potential applications in the field of material processing and heat mass transfer. His work (with P. Cheng and B.H. Chao) on the effect of chemical reaction on the onset of convection gives the ignition conditions that are missing in the work of Frank-Kamenetskii (Diffusion and Heat Transfer in Chemical Kinetics, Penum, 1969). His work on double diffusive convection including cross diffusion effects are noteworthy. Dr. Malashetty has done extensive work on how the absence of local thermal equilibrium affects the convection in porous medium with rotation, mechanical and thermal anisotropy, second diffusive component for viscous and viscoelastic fluids. These works are first in the literature and have appeared in international journal of repute like Physics of Fluids, Int. J. Heat Mass Transfer, Int. J. Thermal Sciences and Continuum Mechanicsand Thermodynamics etc. Most of his works on porous media are reviewed by Nield and Bejan in their book Convection in Porous Media (3rd Ed. Springer, 2006). Dr. Malashetty reviewed research papers for the Journal of Fluid Mechanics, Proc. Royal Soc. Int. J. Non Newtonian Fluid Mechanics, Int. J. Heat Mass Transfer, Int. J. Thermal Sciences, ASME Heat Transfer, etc.

The main area of the nominee’s(M.A.Sofi)research has been functional analysis in which he has made significant contributions to the theory of vector measures and the structure of nuclear Frechet spaces. He started his research career with his contributions to the theory of bases in nuclear Frechet spaces which formed the main theme of his Ph.D thesis submitted at IIT Kanpur. Here, he was able to establish a close connection between the properties of a Schauder basis and the structure of the Fechet space containing it. This work which subsumes the earlier work of Dynin and Mityagin on absolute bases in nucleat Frechet spaces had appeared in 1982-84. More recently, Sofi has been actively working on certain aspects of the theory of vector measures taking values in Banach/Frechet spaces. One of the hitherto intractable problems belonging to this circle of ideas pertains to the localization of (bounded) sequences in a Banach/Frechet space X inside the range of certain X-valued measures with or without bounded variation. In a series of papers that appeared during the period 2005-2010, he has been able to characterize this phenomenon in terms of the geometry of the space in question. As a sample result of this investigation, he is able to prove that for S(X) consisting of bounded sequences in X and for measures of bounded variation taking values in (a superspace of) X, the Banach spaces that result in the process are precisely those which are (isomorphically) Hilbert spaces.
