🌟 Bio

I am a Ph.D. student in Computer Science at Purdue University, advised by Prof. Tianyi Zhang.

My research interest lies in how to better leverage LLMs to generate code. Standing at the intersection of SE, HCI, and AI, I want to build reliable and helpful code generation systems for users. Specifically, I have three main research goals:

  • developing trustworthy evaluation methods for code generation

  • detecting and mitigating hallucinations in LLM-generated code

  • designing user-friendly interfaces and novel interaction techniques to help users with different backgrounds use code generation tools.
