Dr. Hossein Ameri graduated from Tehran University of Medical Sciences and then served as a physician and managing director of Nahavand Health Network in Iran. He received his ophthalmology and vitreoretinal surgery training in Ireland, where he was also an official lecturer at University College Cork and was a founding member of the Irish Retinal Prosthesis Group. Dr. Ameri then moved to Los Angeles for a research fellowship and became an Assistant Professor of Research Ophthalmology at the Doheny Eye Institute of the University of Southern California. He was involved in preclinical studies of Argus II and the development of wide-field retinal prostheses. In addition, he produced quality research on retinal vascular disease, retinal angiogenesis, and ocular ultrasound.

Dr. Ameri completed his internship in general surgery at Cedars-Sinai Medical Center in Los Angeles and moved to Texas for his ophthalmology residency, during which he simultaneously earned a Ph.D. in neuroscience at the Graduate School of Biomedical Engineering of the University of Texas Medical Branch. Dr. Ameri obtained additional fellowship training in vitreoretinal surgery at USC Roski Eye Institute. An accomplished researcher and scholar, he has numerous peer-reviewed publications, holds a number of U.S. patents, and serves on the editorial board of journals. Currently, his lab is focused on developing gene therapy for acquired and inherited retinal diseases such as age-related macular degeneration, diabetic retinopathy, retinal vein occlusion, and retinitis pigmentosa.
