My laboratory studies molecular mechanisms regulating dietary vitamin A transport to the eye and protein trafficking in photoreceptors, in the support of phototransduction and neural visual function. I apply state-of-the art structural biology, genomics, biochemical, and molecular biology technologies, including CRISPR-generated mutant zebrafish and knock-in mouse lines to determine the physiological consequences of low ocular vitamin A and protein mislocalization and its effects on vertebrate RPE, photoreceptor cell health and function, and neuro-auditory function.
