Abheek Ghosh
I am a fourth-year Ph.D. student in Computer Science at the University of Oxford supervised by Profs. Edith Elkind and Paul W. Goldberg. I work in economics and computation, and my recent research has focused on 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 fortunate to be advised by Prof. Umang Bhaskar in voting theory.
