CV, Google Scholar
I am a third-year PhD student in the Computer Science Department at Carnegie Mellon University, where I am fortunate to be advised by Tuomas Sandholm. Prior to CMU, I completed my undergraduate and master’s degrees at Stanford University, where I worked with Greg Valiant.
My current research interests lie in computational game theory, especially equilibrium-finding in large games. I have also done work in adversarial robustness, fairness in machine learning, and quantum computing.
