Background
Research interests include reinforcement learning, information retrieval, and machine learning in general. Recently focused on developing provably efficient and trustworthy reinforcement learning and multi-armed bandit algorithms with applications to recommendation, ranking, LLM agents, and scientific discovery problems in biology and chemistry.
Miscellany
Looking for one self-motivated PhD student with solid math and coding backgrounds starting Fall 2026.
