Associate Professor of Computer Science

University of California at Berkeley

I am a professor in the Computer Science Division of the Department of Electrical Engineering and Computer Sciences at the University of California at Berkeley. I received my doctorate in Computer Science from the Georgia Institute of Technology.

I am generally interested in most areas of Computer Graphics and Animation. My primary area of research involves the physically based simulation of complex deformable and fluid systems to generate motion for use in computer animation.
