Biography

My current research interests include performance modeling and analysis, code optimization, and characterization of current high performance computing (HPC) platforms. As a member of the Application Performance Modeling and Anaylsis Team, we are using the knowledge of current architectures to predict performance of future machines and to try to influence those designs. My background working on several code projects involving porting codes to then current HPC platforms has enabled me to work with many codes on new machines.

Education

Ph.D. in Applied Mathematics, University of Virginia, 1989
Masters in Applied Mathematics, University of Virginia, 1986
B.S. in Mathematics and Physics, Marietta College, 1984
