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 study language processing, dialogue, and decision-making.
My work is computational in two ways. (1) I use data science techniques for inference from large-scale datasets
and experiments. (2) I create computational, cognitive and statistical models to contribute to a unified theory of cognition.
My work in cognitive science is aided by
computational linguistics; my research in computer science is
inspired by cognition.
My research group is primarily supported by the National Science Foundation (several recent projects).

Action&Cognition + Robust Intelligence): Inference of
the syntactic and semantic relationships between
words from an untagged corpus using a
