Research Interests
I'm an assistant professor in the Department of Computer Science at the University of Virginia and a member of the Computer Graphics Group. My research interests include: acquisition of real-world shape and appearance appearance representation and material design global illumination and interactive rendering algorithms 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.
