Bio
He is a principal researcher at Microsoft Research which he joined in 1994 from Princeton University where he served on the faculty of Computer Science. He also served on the Architecture faculty at Cornell University and was an adjunct faculty member at the University of Utah. His early work at Cornell and Princeton on the radiosity method for realistic image synthesis is discussed in his book “Radiosity and Image Synthesis” (coauthored by John R. Wallace). For this work he received The 1998 SIGGRAPH Computer Graphics Achievement Award. His work at the University of Utah focused on spacetime control for linked figure animation. At Microsoft, he has worked on a number of projects ranging from image-based rendering, to animation, to camera control, to artistic nonphotorealistic rendering, and most recently to computational photography applications. One project focuses on the problem of image-based rendering; capturing the complete flow of light from an object for later rendering from arbitrary vantage points, dubbed The Lumigraph. He also continued his earlier work on linked figure animation, focusing on means to allow simulated creatures to portray their emotional state. For the past decade, he has focused on computational photography applications. These range from creating new methods for low bandwidth teleconferencing, segmentation and matting of images and video, technologies for combining a set of “image stacks” as a Photomontage, to the creation of very high-resolution panoramas. Much of this work is summarized in his concept for The Moment Camera. He is a member of the IEEE.
