About Me
I am a PhD candidate in Computer Science at ETH Zurich, supervised by Prof. Niao He. My research focuses on the mathematical theory of reinforcement learning and multi-agent systems, with a focus on mean-field games. I am broadly interested in questions at the intersection of machine learning, optimization, and game theory.
News: I’ll be joining Jane Street’s London office as an intern in Summer 2025. I’ll also be presenting my work, “Exploiting Approximate Symmetry for Efficient Multi-Agent Reinforcement Learning,” at the Learning for Dynamics & Control (L4DC) conference at the University of Michigan from June 4–6, 2025.
Research
I work on the theory of multi-agent reinforcement learning (focusing on mean-field games and mean-field RL). This includes:
- Fundamental hardness of MF-RL
- Provably efficient algorithms for MARL with many agents
- Connections to game theory, optimization, learning theory.
