Research Overview

The overall objective of our laboratory is to understand the molecular mechanism(s) of specific retinal and neurodegenerative diseases with the goal of developing pharmacological therapies. The current projects in the laboratory are focused on delineating the molecular and cellular basis of specific diseases that affect the outer retina including inherited and age-related macular degeneration. The approach to studying retinal physiology and disease development in the laboratory is utilizing patient-derived human induced pluripotent stem cells (hiPSCs) is summarized in the following schematic:
