About me

I am currently a researcher at ByteDance TRAE Research, focusing on AI Coding research. I received my Ph.D. degree in Computer Science from ShanghaiTech University in 2023, under the supervision of Prof. Fu Song. During my Ph.D. studies, I was fortunate to be a visiting student at Singapore Management University, working with Prof. Jun Sun.

My current research interests are centered on AI Coding. This includes designing and evaluating Coding Agents from a software engineering (or formal verification) perspective, exploring the characteristics of LLMs on coding tasks to push their capability boundaries, token-saving strategies for Coding Agents, and the training of Code LLMs.
