Research Description

The research focus of my laboratory is understanding vision loss in retinal degenerative diseases. We study the pathophysiology of photoreceptors including intrinsically photosensitive retinal ganglion cells (ipRGCs) in mouse retinal degeneration models. Our goal is to identify key molecular pathways that underlie photoreceptor cell death and test if these pathways provide potential targets for future retinal therapies.
