My main interests are in the area of human visual perception. I study the way in which visual scenes are organized into something meaningful via processes like figure-ground organization and Gestalt grouping. I also do research in other areas within cognition, including implicit perception, visual perception in autism, and the effects of video games on critical thinking skills.
