I’m a Research Scientist at Meta Superintelligence TBD Lab. I recently defended my PhD at CMU, advised by Maarten Sap, and received a Microsoft PhD Fellowship.
My goal is to build AI agents that help each of us realize our potential. To work well with people, agents need to (1) help us get things done (WebArena, TOM-SWE); (2) understand people and society (OdysSim, Social World Models, Sotopia); and (3) act safely and respect human values (HAICOSYSTEM, OpenAgentSafety).
