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.
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.
