Research Interests
Develop and apply interactive computer graphics techniques for the representation and exploration of quantitative information, the manipulation of virtual objects and representations, and the modeling of objects and their behaviors. Investigate the power of color, texture, motion, and interactivity as display parameters for the visual representation of multivariate data. Develop and experimentally evaluate visualization techniques based on perceptual principles. Collaborate with researchers in other quantitative fields in the application of computer graphics techniques to problems in their disciplines.

Education
May 1993:
Ph.D in Computer Science with emphasis on computer graphics. University of North Carolina, Chapel Hill. Dissertation title: Dynamic Exploration of Multiple Variables in a 2D Space. My research investigated the proposition that dynamic manipulation of color parameters is more powerful than viewing static images for exploring relationships in multivariate data. Experimental findings supported that claim. Advisor: Frederick P. Brooks, Jr.

December 1988:
M.S. in Computer Science. University of North Carolina, Chapel Hill.

June 1985:
B.A. in Computer Science. Harvard University.
