Andrew McCallum is an Associate Professor in the Computer Science Department at University of Massachusetts, Amherst. From 2000 to 2002, he was Vice President of Research and Development at WhizBang Labs, and Director of its 30-person research and development lab in Pittsburgh, PA. Prior to joining WhizBang he was a Research Scientist and Research Coordinator at Just Research (Justsystem Pittsburgh Research Center).
