I have 25 years of experience in the field of vision science, with specific knowledge in the areas of retinal disease and visual function, aging and visual function, and ophthalmic devices. I have published on such topics as visual neuroscience, visual psychophysics, and retinal imaging. I have testified on safety and efficacy of ophthalmic devices. I have received international awards for research on a variety of vision science areas such as ophthalmology, low vision, visual neuroscience, and device development.
