I am a research scientist at GE Global Research Center, Visualization and Computer Vision Lab. I got my Ph.D. from Purdue University, where I worked with Prof. Daniel G. Aliaga and was affiliated with the CGV Lab. My research interests are computer graphics and computer vision, including image-based rendering and modeling, 3D acquisition for moving and deforming objects and for objects with complex optical effects, interactive computer graphics and computational photography. In Summer and Fall 2008, I worked at MERL as a research intern hosted by Dr. Amit Agrawal.
