Research Area: My work is in the areas of analog/digital/mixed-mode circuit design, VLSI, FPGA's (Field Programmable Gate Arrays), and computer vision/image-processing applicable to retina prosthesis develoment. The project which I represent is a joint research effort between ophthamologists/surgeons and researchers at Johns-Hopkins University and electrical engineers/researchers at North Carolina State University. Our goal is the development of a chronic retina-prosthesis implant to restore some vision to people who are blind due to outer-retinal degeneration caused primarily by the two diseases Retinitis Pigmentosa and Age-Related Macular degeneration
