I am currently a first-year PhD student at Siebel School of Computing and Data Science, University of Illinois Urbana-Champaign advised by Jiaxuan You. I also work closely with Paul Pu Liang. My main research interests lie in language agents and automatic research.

Before UIUC, I got my B.Eng. degree in Computer Science (with honors) at ChuKochen Honors College of Zhejiang University. Afterwards, I got my M.S. in Intelligent Information Systems in Language Technologies Institute of School of Computer Science at Carnegie Mellon University.

I have multiple industrial internship experiences including Tencent AI Lab (2022 Summer), Apple Siri Information and Intelligence Team (2023 Summer), and MIT-IBM Watson AI Lab (2024 Summer). All focusing on language modeling and its applications (long-context, QA, agents).
