I am an Assistant Professor at Harvard's Department of Psychology. I study computation, cognition, and development, with a focus on intuitive theories and people's common-sense reasoning about physics and psychology. I'm also a member of the Center for Brains, Minds and Machines.


My thesis was on the nature and origin of intuitive theories, available here.
