About Me
Hello, I am Yaxun Dai, a graduate student (Class of 2026) at Soochow University, under the supervision of Associate Professor Pingfu Chao. My research interests focus on reasoning enhancement for large language models (LLMs), Text-to-SQL, and table reasoning.
I am currently seeking Ph.D. opportunities for Fall 2026. My research interests include improving the reasoning capabilities of large language models, especially in table-related tasks such as Text-to-SQL.
