I am an associate 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 systems to generate motion for use in computer generated animation.

      Information about my research projects can be found on the Berkeley Computer Animation and Modeling web pages.

A list of my publications can be found on my publications page.

Recent Awards: Fifteen Year Impact Award, GVU Center, Georgia Institute of Technology. College of Engineering Distinguished Alumni, Florida International University. Technology Review TR100. Sloan Fellowship.
