I work on problems in computer vision, computational photography, and machine learning—dealing with the design of accurate and efficient algorithms for visual inference, and of new kinds of high-capability sensors and cameras. I seek solutions to these problems by considering the physics of image formation, and the statistical structure of natural images and scenes.
