Overview

James Weiland received his B.S. from the University of Michigan in 1988. After 4 years in industry with Pratt & Whitney Aircraft Engines, he returned to Michigan for graduate school, earning degrees in Biomedical Engineering (M.S. 1993, Ph.D. 1997) and Electrical Engineering (M.S. 1995). He joined the Wilmer Ophthalmological Institute at Johns Hopkins University in 1997 as a postdoctoral fellow and, in 1999, was appointed an assistant professor of ophthalmology at Johns Hopkins. Dr. Weiland was appointed assistant professor at the USC Eye Institute-University of Southern California in 2001. Currently, Dr. Weiland is Professor of Ophthalmology and Biomedical Engineering, University of Southern California. He is Deputy Director of the Biomimetic Microelectronic Systems Engineering Research Center. Dr. Weiland’s research interests include retinal prostheses, neural prostheses, electrode technology, wearable technology for the blind, visual evoked responses, and implantable electrical systems. He is a Fellow of the American Institute of Medical and Biological Engineering and a Senior Member of the IEEE EMBS.
