The research in Dr. Viswanathan’s lab focuses on understanding the mechanisms underlying visual dysfunction in glaucoma and mild traumatic brain injury and developing clinical tests for the detection and monitoring of neuronal dysfunction in these conditions. These investigations use electrophysiological, psychophysical and in vivo imaging techniques.
