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

My research focuses on enhancing the robustness, privacy and generalization of ML, and the intersection of these topics, especially in language models, generative models and federated learning. 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.
