Welcome!

I pursue research in machine learning, computational statistics, and information visualization. Some of my application areas are text documents, ranked preference data, privacy preservation in databases and social networks, and modeling risks in computer security. I am also interested in analyzing financial and biological data and images.

I completed my PhD in 2005 at the School of Computer Science of Carnegie Mellon University working with John Laffrety. I then joined Purdue University as an assistant professor of statistics and electrical and computer engineering. In August 2008 I joined the CSE division of Georgia Tech's College of Computing.
