Third-year Ph.D. student

McCombs School of Business, The University of Texas at Austin

I am a third-year Ph.D. student at the McCombs School of Business, The University of Texas at Austin, advised by Prof. Mingyuan Zhou.

Previously, I received my M.S. from the Institute of Automation, Chinese Academy of Sciences (CASIA) in 2023, and my B.S. in Software Engineering from Dalian University of Technology in 2020.

My research interests include large language model alignment, reasoning, and post-training optimization.

If you are interested in my work and would like to collaborate, please feel free to reach out!
