I am a research associate at The Alan Turing Institute in the UK, where I am working with Prof. Rahul Savani and Prof. Theodore Turocy on the project "Automated Analysis of Strategic Interactions". I received my Ph.D. from the Department of Computer Science at the University of Michigan, advised by Prof. Michael P. Wellman.
My research interest focuses on multi-agent learning with game-theoretical approaches, reinforcement learning, and machine learning.
