I am Xuanchang Zhang (章轩畅), a first-year PhD student at the University of Illinois Urbana-Champaign, advised by Prof. Tong Zhang.

My research focuses on post-training and alignment of large language models, with an emphasis on reinforcement learning. My recent work focuses on training LLMs with reinforcement learning using off-policy data.

I received my B.Eng. in Computer Science from Shanghai Jiao Tong University, where I was a member of the ACM Honors Class. During my undergraduate studies, I worked with Prof. Zhuosheng Zhang and Prof. Hai Zhao at SJTU, and later with Prof. Tong Zhang at UIUC.
