About

I am currently a computer scientist with the Future Technologies Group in the Computer Science and Mathematics Division of Oak Ridge National Laboratory. I research next-generation computing architectures, including evaluating GPUs for general purpose computation, and I am a founding member of the development team for the VisIt scientific visualization application. Before coming to ORNL, I worked for Lawrence Livermore National Laboratory. I received my MS in Computer Science from Stanford University and my BS from the University of Illinois at Urbana-Champaign.

Awards I have received include the 2008 ACM Gordon Bell Prize, 2005 R&D 100 Award, and the DOE/NNSA Defense Programs Award of Excellence in 1999 and 2002.
