Seth Karten

I am a PhD Candidate in Computer Science at Princeton University advised by Chi Jin. My current research interests involve developing foundation agents that can perform closed-loop decision-making in open-ended environments at scale. Much of my research is focused on studying agents in complex envionments to limit-test fundamentals while enabling rich applications in embodied agents and economic systems.
