Sushmita Bhattacharya

Sushmita

I am a Ph.D. candidate in the Computer Science department at Harvard University. I am a member of REACT lab and working under the guidance of Dr. Stephanie Gil. My research focuses on designing multiagent reinforcement learning algorithms to solve real-world sequential decision-making problems under realistic computation and communication constraints. As a part of ProjectCETI, I work on multiagent RL-based autonomous routing with application to marine life observation.
