Research Interests

Our research focuses on vertebrate eye development, disease and regeneration utilizing the zebrafish as a model system. Combining forward genetic screens with reverse genetic and embryological manipulations we hope to understand the molecular, cellular and developmental events that regulate eye formation and visual function. Current areas of interest in the lab include studies focusing on the development and maintenance of the lens, retina, hyaloid vasculature and retinal pigmented epithelium of the eye, and elucidation of the molecular and cellular mechanisms that regulate ocular morphogenesis and regeneration Our research combines molecular, cellular, biochemical, transgenic and in vivo imaging techniques to address these questions. It is our hope that these studies will ultimately lead to a better understanding of visual system disorders such as macular degeneration, retinal degenerations, cataracts and ocular colobomata that often result in blindness in afflicted patients.
