Back to BiologyBack to Biology• Went to high school in north western

New Jersey

• BA in Biological Sciences from the University of Delaware

• Before graduate school I designed and built fiber optic networks for computer storage arrays and managed UNIX servers

• Currently in my 4th year of study for my PhD in Molecular Biology

The LensThe Lens

bovine (cow) lens

• Transparent tissue composed of specialized cells

• Focuses light in the eye

• Surrounded by a selectively permeable membrane called the lens capsule

• My research focuses on the mechanisms behind the selective permeability of the lens capsule

Important to Understand Selective Important to Understand Selective Diffusion in the Lens CapsuleDiffusion in the Lens Capsule

• The lens is not directly fed by blood vessels

• Nutrients and other molecules required by the lens to develop and grow must diffuse through the capsule

• Protect the lens from bacterial and viral invasion

• My research will help understand how other organs filter molecules
