He is starting a new group in the department for research in graphics and animation, including the design of a new curriculum in graphics and a new graduate course in computer animation. His research interests include computer animation, computer graphics, user interfaces and computer vision. A current project involves the application of spacetime constraint methods to motion editing and tracking. Prior to joining the faculty at Wisconsin, he was a research scientist at Autodesk and Apple. He was awarded a Ph.D. in computer science from Carnegie Mellon University for his work on constraint-based user interfaces, and also received an M.S. in computer science from CMU and a B.S.E. in electrical engineering from Duke University.
