I joined Georgia Tech in August 2007 in School of Interactive Computing. Before moving to Atlanta, I was an assistant professor at the University of Southern California from January 2006, after I received my Ph.D and M.S. in 2005 and 2001 from the University of Washington. My research interests are in computer graphics and animation, including physics-based animation, character animation, optimal control, numerical methods, robotics and computational biomechanics. My Ph. D. thesis focuses on designing a generative model for human natural motion. I am a member of the Graphics Lab at Georgia Tech.
