I am a third-year(2023 Spring-now) Ph.D student in Mine Lab in Computer Science at University of Notre Dame, advised by Prof. Xiangliang Zhang. I’m also a graduate student in Foundation Models and Applications Lab (FMAL) at Lucy Family Institute for Data & Society. Before this, I received my B.E. degree in Computer Science and Engineering at the University of Electronic Science and Technology of China (UESTC) and my M.S degree in Computer Science at King Abdullah University of Science and Technology (KAUST).

I am deeply interested in Large Language Model (LLM) Reasoning and trustworthy LLMs. I aim to understand how LLMs reason, where their reasoning fails, and how to enhance their ability to generalize beyond seen problems. In parallel, I study how to make LLMs more reliable, safe, and aligned when applied to safety-critical contexts. Also, I am engaged in ND-IBM Tech Ethics Lab Collaborative Project, where I explore ways to extend the trustworthiness of LLMs to practical domains such as laboratory safety and investigate the misalignment behaviors.

I am seeking potential research collaborations and the position of industry research intern. If you are interested, please contact me.
