Research interests

My research interest are in the area of 3D computer graphics and vision, image based rendering and computer animation. I am affiliated with the computer graphics lab, and am currently advised by Steve Seitz and Takeo Kanade.

Research interest keywords

Past Labs & Groups

Computer Graphics Lab - Modeling, animation, and rendering of 3-D scenes	Face Group - Robust detection, recognition, and tracking of human faces with automated analysis of expressions
Human Identification at a Distance - We are developing and evaluating human identification technologies as part of the Defense Advanced Research Projects Agency (DARPA) sponsored program in Human Identification at a Distance (HumanID).

Past Projects

2D->3D Face Model Construction - We develop a linear algorithm that uniquely recovers the 3D non-rigid shapes and poses of a human face from a 2D monocular video.
