Hello!

I am a final-year Ph.D. Candidate in Natural Language Processing group at The Ohio State University. I am fortunate to be advised by Prof. Huan Sun. Previously, I did my internship at IBM Research in 2022 and Adobe in 2024. Prior to OSU, I received B.S. in CSE from University of Electronic Science and Technology of China, and was a research intern in UCLA, working with Prof. Fabien Scalzo.

My primary research lies in the area of natural language processing and machine learning. Specifically:

• Large Language Models and Agents: post-training, evaluation, analysis, data engineering, and LLM-based agent framework design.
• Natural Language Interface: building advanced natural language interfaces to tables and relational databases (a.k.a. semantic parsing, table QAs).
• Learning Paradigm: instruction tuning and federated learning.

I’m actively looking for a job in industry starting in 2026! Please feel free to reach out if you’d like to discuss potential opportunities.
