Abheek Ghosh
I am a postdoc researcher at the University of Oxford, advised by Prof. Paul W. Goldberg. I completed my Ph.D. also at Oxford, supervised by Profs. Edith Elkind and Paul W. Goldberg. I work in economics and computation, and my recent research has focused on computational complexity, contest theory, and learning dynamics in games. I spent a summer working with Prof. Milind Tambe and the AI4SG and MLO team at Google Research on problems related to multi-armed bandits. Prior to joining Oxford, I was advised by Prof. Umang Bhaskar in voting theory. I did my undergrad at IIT-Guwahati and master's at UT-Austin.
