University of California, Los Angeles

I am a second-year PhD student in Computer Science at SCAI Lab, UCLA, where I am fortunate to be advised by Prof. Wei Wang.

Previously, I earned my bachelor’s degree at ACM Honor Class, Shanghai Jiao Tong University. I had a wonderful time as an undergraduate researcher advised by Prof. Weinan Zhang at SJTU APEX Lab and Dr. David Wipf, Quan Gan, Dr. Minjie Wang at Amazon Shanghai AI Lab.

I am broadly interested in Agentic RL, LLM post-training, and LLM agents.
