About Me

I am a first-year CS Ph.D. student at the University of Illinois Urbana-Champaign (UIUC), advised by Prof. Xiaojing Liao. My research focuses on Reliable AI, aiming to enhance the robustness, transparency, and regulatory compliance of LLMs and autonomous AI agent systems. I also worked on IoT and Network robustness.

Previously, I received my B.E. and M.S. degrees from Tsinghua University. I served as a volunteer middle school teacher in Xinjiang, Tibet, Shanxi, and Fujian, China.
