What is a GDR, what for?�

•� Group of teams gathered together for organizing a scientific community

working on an emerging research field and undertaking a cooperative

research on targeted priorities�

•� Financial grant from the CNRS for networking, not usable for research�

•� Additional grants from agencies fro specific actions�

GDR = Groupe De Recherche (Group of Research)�

Objectives:

- open platform for promoting exchanges, initiating research projects �� - sharing samples and materials, facilities, expertises�� - training and mobility of phD students and young scientists�� - communication and dissemination�

Page 3: GDR GNT and GDR -I GNT A tool of the CNRS for a federative ...

•� Organization of annual meetings, thematic workshops and schools

•� Support to mobility and training

•� Grants to promote exchanges between partners for performing

experiments, calculations or discussions�

•� Grants for PhD students for attending scientific meetings �

� supported or organized by the GDR�
