I am a 4th-year Ph.D. student in Computer Sciences and Engineering at the OSU. I am very fortunate to be advised by Prof. Ness Shroff. In Spring and Summer 2022, I spent a wonderful time as a visiting student in AINet-Lab at ZJU, supervised by Prof. Yang Yang. Before joining the OSU, I graduated from the Department of Mechanical Engineering at SJTU.

My research interests include stochastic process, bandit learning and reinforcement learning. Currently, I'm particularly interested in RLHF under corrupted human feedback.
