About me
Hi! I am a third-year Ph.D. student at the Department of Electrical Engineering and Computer Science of the University of Michigan, Ann Arbor. I'm very fortunate to be advised by Prof. Lei Ying. Before joining U of M, I received my B.S. degree from Tsinghua University in 2021, mentored by Prof. Jintao Wang. and Dr. Haoyue Tang.
Research
I have been working at the interplay of multi-armed bandits, reinforcement learning, stochastic approximation, and networked systems. My research includes:
Reinforcement Learning from Human Feedback
Efficient algorithms for regret optimal best policy identification
Offline stochastic bandits and reinforcement learning with hard operation constraints
Approximation and optimal control of mutated diffusion processes
Age-of-Information aware scheduling in wireless networks
