I am an Assistant Professor at Department of Computer Science and Engineering, University of California, Riverside. I completed Ph.D. at UCLA in 2025, advised by Prof. Cho-Jui Hsieh, and I received my Bachelor’s degree from Tsinghua University in 2020.

My research focus is on machine learning, especially developing more trustworthy and reliable AI models. Recently, I have been working on formal methods for AI, trustworthy AI, and LLM post-training.

Prospective Students: I am looking for motivated students to join my group. See this page for details.
