I am a professor in the Computer Science Department and a member of the Graphics Group and Princeton ImageX Labs (PIXL). I am also associated faculty in the Program in Applied and Computational Mathematics. My work focuses on the interface between computers and the visual and tangible world: acquisition, representation, analysis, and fabrication of 3D shape, motion, surface appearance, and scattering. I am interested in topics including computational fabrication; 3D scan acquisition, registration, and reconstruction; learning for low-level image and shape analysis; robotic localization and planning; and BRDF capture and representation. Applications of this work include documentation of cultural heritage artifacts and sites, appearance and performance capture for digital humans, and illustrative depiction through line drawings and non-photorealistic shading models.
