Steve Massey received a Ph.D. in Neuropharmacology from the School of Pharmacy at London University in 1980. He moved to the US and completed post-doctoral work with Dianna Redburn, working on cholinergic amacrine cells in the retina, at the University of Texas in Houston and then with Robert Miller, studying glutamate receptors in the retina, at Washington University in St. Louis. In 1985, Steve joined the faculty at the University of Texas in Houston where he is now Professor and Research Director in the Ruiz Department of Ophthalmology and Visual Science at McGovern Medical School. Steve’s group studies rod and cone pathways in retinal circuitry. The current focus is on photoreceptor coupling via gap junctions in collaboration with Dr. Christophe Ribelayga. Methods include physiology, confocal and 2 photon microsocopy and serial blockface reconstruction of retinal circuits.
