Hi! I am a third-year Ph.D. student in Computer Science at University of Illinois at Urbana-Champaign, advised by Prof. Bo Li.

My research focuses on enhancing the security/privacy/generalization of ML, and the intersection of these topics, especially in federated learning and language models. Previously, I received my Bachelor degree from Computer Science department at Zhejiang University in July 2020. I was a research intern at Microsoft Research and NVIDIA Research.
