Degrees

Ph.D., University of California, Berkeley
B.A., Macalester College

Main Interests

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.

Research Interests

Visual perception, figure-ground organization, Gestalt grouping factors, implicit perception.

Teaching Interests

Perception, cognition, memory, experimental lab, consciousness

Other Interests

Traveling, home improvement, good food, visual illusions
