I am Professor of Computer Science at the University of Toronto, and Chair of Computer and Mathematical Sciences at the University of Toronto Scarborough. I joined the University of Toronto in October, 2003. Prior to that I worked in the Digital Video Analysis and Perceptual Document Analysis Groups at the Palo Alto Research Center (PARC) for 4 years. Before that I was on faculty at Queen's University in Kingston.
I served as Associate Editor (2000-2003) and then as Associate Editor-in-Chief (2004-2008) for IEEE Transactions on Pattern Analysis and Machine Intelligence (PAMI). I also served as Program Co-Chair of IEEE CVPR (2003), ECCV (2014), and as Area Chair for numerous vision and learning conferences (CVPR, ECCV, ICCV, NIPS, ICML). At present I serve on the Advisory Board for IEEE PAMI, and I am a Senior Fellow of the Canadian Institute for Advanced Research (CIFAR).
My research interests include aspects of computer vision, image processing, visual perception and visual neuroscience. Most of my specific research has focused on mathematical foundations and algorithms for visual motion analysis, tracking, human pose and motion estimation, and models of motion perception and stereopsis.
