I am a Professor of Computer Science in the Department of Computer Science, located at NC State University in Raleigh, North Carolina. My research focuses on investigating visualization techniques that support rapid, accurate, and effective exploration and analysis of large, complex, multivariate datasets. Many of our approaches harness visual perception. This allows much of the analysis to be performed automatically by the low-level visual system. More recently, I have been investigating machine learning for natural language processing and text analytics.
