Biography and Research Activities
I'm an associate professor in the Department of Computer Science at the University of Virginia and a member of the Computer Graphics Group. Prior to joining UVA in the Fall of 2006, I was a member of the Princeton Computer Graphics Group. Additional information is contained in my CV. My main research activities include: General Appearance Capture Material Representation Date Reuse in Real-Time Rendering Systems Internet Scale Image Processing
