Dr. Cohen received his Ph.D. in retinal neuroanatomy in 1987 at U. Penn. Med. School in the lab of Dr. Peter Sterling. After post-doctoral fellowships at UCLA and the Univ. of Minn. with Gordon Fain, and Robert Miller, he joined the faculty of the Ophthalmology Dept at Yale University in 1992. After a visiting professorship at Harvard University with Dr. John Dowling, he joined FDA in 2003.

My medical device research focuses on projects that evaluate the safety and efficacy of cutting edge neuroprosthetic therapies for blindness. Our lab is currently developing novel methods of evaluating new electrical and optical stimulation therapies for retinal neurons, particularly using imaging methods of retinal tissue in real time.
