How does the mind work? I would like to understand what makes us intelligent, and why we make mistakes at times. As a computional cognitive scientist, I have contributed to our understanding of language processing in the context of dialogue, to artificial intelligence, and, more recently, to decision-making. I primarily create computational models via inference from large-scale datasets and experiments. My work in cognitive science is aided by computational linguistics; my contributions to computer science are inspired by cognition.

Our work is primarily supported by the National Science Foundation (several recent projects), with some additional projects made possible by the U.S. Air Force.
