Hello, my name is Changyin Zhou. I am a Ph.D student in the CAVE lab of Computer Science Department, Columbia University. My advisors are Prof. Shree K. Nayar and Prof. Peter Belhumeur. My current research interests in computer vision include computational imaging and physics-based vision.

Before coming to Columbia University, I have got my M.S. in Computer Science and B.S. in Statistics, both from Fudan University, China. I worked for Microsoft Global Technical Engineering Center as an engineer from 2001 to 2003, and worked for Microsoft Research Asia as a visiting student from 2006 to 2007, supervised by Dr. Stephen Lin.
