School of Medicine
Debasish Sinha, M.S., Ph.D.
Director, Glia Research Laboratory
Associate Professor of Ophthalmology
Research Interests: Age-related macular degeneration, Retinal cell biology, Glial cells
Debasish Sinha, Ph.D., is an associate professor of ophthalmology at the Wilmer Eye Institute, Johns Hopkins University School of Medicine, with a joint appointment in the Department of Environmental Health Sciences of the Bloomberg School of Public Health. He received his Ph.D. degree in immunology and did a postdoctoral fellowship in molecular biology and genetics at the National Eye Institute.
His laboratory uses rat spontaneous mutants and genetically engineered mice as genetic tools to explore the functions of glial cells during normal neuronal and vascular development and to probe how abnormalities in glial cells lead to central nervous system diseases. In addition, his laboratory is also interested in understanding the processes of autophagy and phagocytosis in retinal pigmented epithelial cells and regulation of the immune system in age-related macular degeneration. His research is funded by the National Institutes of Health, Research to Prevent Blindness and private foundations. Dr. Sinha received the Sybil B. Harrington Special Scholar award for Macular Degeneration from Research to Prevent Blindness.
