I am a graduate student at the Lab For Developmental Studies at Harvard. Before that, I received my undergraduate degree in Psychology from Dartmouth College. My research centers around the origins of social intelligence, at the level of description that could inform machine intelligence. Specifically, I study the representations and computations supporting our earliest understanding of the beliefs, goals, and costs motivating other people's actions. My research is funded by the Center for Brains, Minds and Machines and the NSF Graduate Research Fellowship Program.
