| I am a PhD student in the Computer Science
Department of Columbia University. I am
a member of the CAVE lab and the
Graphics
lab. My advisers are Prof. Shree Nayar,
Prof. Peter
Belhumeur, and Prof. Ravi
Ramamoorthi. Before I came to Columbia University, I
got a B.S. and M.S. from Department of Automation at
Tsinghua
University in China. I had also been a visiting
student in Microsoft Research
Asia from 2003 to 2004, and an intern student in Adobe
Research (CTL lab) in the summer of 2008. |
My research interests are computer vision and computer
graphics. I am particularly interested in
understanding and modeling the physics-based image
formation mechanism and the intrinsic structure of the visual
appearance of various types of natural phenomena,
and applying them in:
- Data-Driven Computer Graphics for
acquiring and recreating realistic visual appearance
of natural phenomena;
- Physics-based Computer Vision for recovering higher-level
information such as geometry, material
properties, and illumination;
- Computational Photography for capturing
high-quality, information-rich photographs and videos.
