My research focuses on the physics of computer vision and computer graphics. My projects highlight three main aspects of my research – the mathematical modeling of the interactions of light with materials and the atmosphere; the design of novel cameras with higher resolution in space, color and intensity; and the development of algorithms for rendering and interpreting scene appearance. My research is motivated by applications in a wide range of fields including robotics, digital entertainment, remote sensing and underwater imaging.

My research projects.
