I am a research scientist, technical lead, and engineering manager at Google in Seattle where I lead a team working on the future of communication. Prior to joining Google, I was associate professor of computer science at the University of Virginia. I hold a PhD in computer science from Princeton University and a BS in electrical engineering from Carnegie Mellon University.
My research spans computer graphics, computer vision, and machine learning. I have worked on a wide range of problems in physically-based rendering, real-time rendering, material appearance modeling and representation, computational fabrication, and acquisition of 3D geometry and material properties. My recent work has focused on high-fidelity real-time 3D capture, 3D display technologies, and digital relighting.
