Chejian Xu

I am a first year Computer Science Ph.D. student at University of Illinois, Urbana-Champaign (UIUC), advised by Prof. Bo Li. I received my Bachelor's degree from Computer Science, Zhejiang University at CKC Honors College, advised by Prof. Shouling Ji and Prof. Siliang Tang.

My current research interests lie at the intersection of trustworthy machine learning and reinforcement learning, with the goal of developing robust machine learning systems.
