Greg manages the TACC Visualization and Data Analysis (VDA) group. Simultaneously, he is a Ph.D. student in the Department of Computer Sciences. His research is focused on advancing the algorithms and architecture commonly used in real-time computer graphics (as in the visualization of scientific data).
Greg also participates in the evaluation of high-end hardware and software systems, and the planning and execution of visualization-related events including training and outreach.
Prior to arriving at TACC as a research associate in 2001, Greg served as an associate staff scientist at the San Diego Supercomputer Center at the University of California San Diego. There he conducted graphics and visualization-related research that contributed to the development of a highly-tuned parallel volume rendering system. This system is currently used to generate high-quality content for the seven-projector digital dome of the Hayden Planetarium at the American Museum of Natural History in New York.
