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 computational photography. During Summer and Fall 2008, I was working at MERL as an intern hosted by Dr. Amit Agrawal.

I served as the Publicity Chair on the I3D 2009 conference committee. I am also a Program Committee (PC) Member for I3D 2009 and I3D 2010 .
