Research interests

My research interests span all combinations of lights, cameras and computers for application in vision and graphics. Specifically my work has three areas of focus. First, modeling a scene's visual appearance to find material, geometric or illumination invariant features for data-driven and learning algorithms. Second, applying active illumination to recover geometry and create novel visual experiences. Third, exploiting vision algorithms and psychophysics techniques to understand, enhance and edit stereographic content.
