🌟 Bio

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