About me

I am a final-year Ph.D student, advised by Prof. Chunyan Miao. I received my B.Eng. degree in Electrical Engineering and B.A. degree in Economics in July 2021.

My research aims at bridging programming language and natural language. Specifically, I focus on code search (code retrieval) [RACS’22, Soft-InfoNCE’23], code generation [GiFT’25], and the synergy of the two through Generation-Augmented Retrieval [ReCo’24] and Retrieval-Augmented Generation framework.

I am on the job market this year! Please feel free to reach out if you’d like to discuss opportunities. You can find my CV here.
