My research interests are computational imaging, 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:
Computational Photography for capturing high-quality, information-rich photographs and videos;
Physics-based Computer Vision for recovering higher-level information such as geometry, material properties, and illumination;
Data-Driven Computer Graphics for acquiring and recreating realistic visual appearance of natural phenomena.
