I have 10 years of experience, and specialize in the field of ophthalmology with specific knowledge in the areas of retina, vitreo-retinal surgery and retinal prosthesis. I have published on such topics as the retinal prosthesis, age related macular degeneration and retinopathy of prematurity. I have testified on child abuse. I helped in the development of a retinal prosthesis that restores vision in individuals blind from retinitis pigmentosa.
