I am working with Prof. Daniel G. Aliaga and affiliated with the CGV Lab. My research interests lie in computer graphics and computer vision, with focus on acquisition, modeling and rendering. This includes image-based modeling and rendering, shape from structured light, and 3D reconstruction of real-world static and dynamic scenes. I am also interested in interactive computer graphics and hardware-accelerated rendering. During Summer 2008, I was working at MERL as an intern under the supervision of Dr. Amit Agrawal.

I am serving as the Publicity Chair on the I3D 2009 conference committee.
