I joined the Computing Science Department of the University of Arizona in the fall of 2003. Previously, I was post doctoral fellow in computer vision at the University of California at Berkeley. I did my Ph.D. in computer science at Simon Fraser University, specializing in colour constancy. My research interests include object recognition and image understanding, the application of computer vision to the organization and effective use of large image collections, physics based vision, and colour issues in vision and image reproduction.
