Philip Kellman

Philip Kellman is Distinguished Professor of Psychology and the current Cognitive Area Chair in the Department of Psychology at the University of California, Los Angeles. He is also Adjunct Professor of Surgery in the David Geffen UCLA School of Medicine, and the founder of Insight Learning Technology, Inc, a company that applies perceptual learning, adaptive learning technology, and principles from cognitive science research to improve education and training. His research interests involve perception and visual cognition, specifically visual perception of objects, shape, space, and motion, and perceptual development. He is also an expert in perceptual learning, adaptive learning, and their applications to skill acquisition and educational technology.

Kellman obtained his Bachelor of Science with high honors from Georgetown University in 1976. From there he earned his PhD from the University of Pennsylvania in 1980. His PhD advisor was Elizabeth Spelke. Upon graduation, he was a professor and Chair of the Division of Natural Sciences and Engineering at Swarthmore College before joining the UCLA faculty in 1993.

Kellman has received a number of national awards for research, including the William Chase Memorial Award from Carnegie-Mellon University, the Boyd R. McCandless Award from the American Psychological Association, and the Wolf Aviation Prize from the Alfred and Constance Wolf Foundation. He is a Fellow of the Association for Psychological Science, the Psychonomic Society, and the Society of Experimental Psychologists.
