Hello!

I am a third-year Ph.D. student 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. Prior to OSU, I received B.S. in CSE from University of Electronic Science and Technology of China.

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

• 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.
• Large Language Models: (pre-)training, evaluation, analysis and data engineering.

I’m actively looking for collaborators. Feel free to drop me an email if you are interested in working with me!
