Education
Ph.D in Computer Science. 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.

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

A.B in Computer Science. Harvard University.

Research Interests
Visualization of spatial and non-spatial data, including the visualization of predictive models, data with associated uncertainty, and data about student success. Visualization based on perception and illustration. Dynamic and interactive representations and interfaces, and the experimental validation of visualization techniques. Computer science pedagogy and gender issues in technology education.
