Preeti Verghese

Senior Scientist

Chief Scientific Officer

Ph.D.

The research in my lab examines the neural processes, strategies and adaptations that humans use to interact with objects in the real world. We investigate these questions using psychophysics, eye movements, computational modeling and neuroimaging. Our goal is to understand the mechanisms of normal vision and action, as well as the basis of attention and visual adaptation in clinical populations. This work includes attention deficits in amblyopia, and the potential for binocular vision in individuals with age-related macular degeneration.
