Hi!
I am a forth-year Ph.D. candidate at University of Illinois Urbana-Champaign (UIUC), under the supervision of Prof. Jiawei Han.
I received my Bachelor's degree from the IEEE honored class, Shanghai Jiao Tong University (SJTU) in 2022. In my undergraduate years, I was advised by Prof. Hai Zhao and collaborated with Zhuosheng Zhang at SJTU.
I am actively looking for research internships for Summer 2026. Feel free to reach out if you think I am a good fit! Research Interests
My research interests lie at the intersection of natural language processing and machine learning.
Generally, I’m interested in the following:
Enhancing complex reasoning ability of LLMs and self-evolving LLM agents;
Post-training of LLMs in a data-centric sense;
AI for Science specifically in the domain of chemistry;
Recent News
09/2025: Check out our paper on memory mechanisms and scaling for self-evolving agent systems!
09/2025: One paper on LLM reasoning is accepted to NeurIPS 2025, and another paper on functional group reasoning is accepted to NeurIPS DB track. See you in San Diego!
01/2025: Two papers on AI software engineering and chemistry reasoning are accepted to ICLR 2025.

Miscellaneous
I love playing the piano. I have been practicing the piano ever since I was 5 (I still try to find time practicing in my Ph.D. journey). I am a crazy fan of Frédéric Chopin, and I am also fond of music pieces arranged by Animenz.
Some of my repertoires include Ballade No.1 Op.23, Polonaise in A-flat major, Op.53, My Dearest, Unravel, and Prelude g-moll, op.23, No.5
I have a cat Turing.
