I am an Assistant Professor in the Department of Computer Science at the University of New Hampshire. Before joining UNH in 2007, I managed the Embedded Reasoning Area and was a member of the research staff at the Palo Alto Research Center (formerly Xerox PARC). I received my PhD from Harvard University in 2002.

My main research is in artificial intelligence, although I also have interests in robotics, cognitive science, operations research, and information visualization. Very broadly, my goal is to understand how to build autonomous systems - for example, how to decide what a robot should do next. I'm also interested in learning from natural examples, such as human cognition. My current focus is on methods for combinatorial optimization, heuristic search, and planning. In particular, I am interested in solving problems quickly (rational time-bounded decision-making) and in how on-line learning can inform optimization algorithms. I also enjoy experimental algorithmics.
