My research interests include multi-agent systems, robust machine learning, and decision-making under uncertainty. I am honored to be a Google AI Impact Scholar (2021) for Social Good.

Before this, I was a postdoctoral research fellow at the Stanford Intelligent Systems Lab at Stanford University, USA, working under Mykel Kochenderfer, where I was awarded the 2019 CARS post-doctoral fellowship by the Center of Automotive Research at Stanford (CARS). Before joining Stanford, I was a Ph.D. student at Vanderbilt University’s Computational Economics Research Lab under Eugene Vorobeychik, working on decision-theoretic and machine learning-based approaches for multi-agent planning. My thesis was nominated for the Victor Lesser Distinguished Dissertation Award 2020.
