Dimitris Margaritis
Assistant Professor
Department of Computer Science
Iowa State University

Education

• PhD in Computer Science, Carnegie-Mellon University, 2003.
• MS in Computer Science, State University of New York at Stony Brook, 1995.
• BS in Physics, University of Athens, Athens, Greece, 1991.

Interests

I work in the area of Machine Learning, Data Mining, and Artificial Intelligence. The question that I am trying to answer is: How can we make computers learn and improve from past experiences in order to solve problems that require intelligence? My current research interests include graphical models, statistical modeling, Monte Carlo estimation, feature selection, non-parametric statistics, learning from centralized or distributed data, and parallel data mining. I am also keenly interested in interdisciplinary applications.
