My lab focuses on understanding the molecular mechanisms underlying the pathogenesis and progression of severe neurodegenerative diseases of the retina.. Specifically, we are interested in diseases that are caused by defects in the transport of proteins from one end of our light sensing neurons called photoreceptors, to the other end. We utilize multiple animal models (mice and zebrafish) to study such diseases and also to utilize them as platform to design treatment modalities.
