I am currently a CS PhD student at University of Utah, advised by Prof. Guanhong Tao. I obtained my B.E. in Computer Science from SUSTech, advised by Prof. Yepang Liu. I also spend a wonderful time as a research assistant at HKUST(GZ), advised by Prof. Xinlei He.

My research interests lie in LLM4Code and LLM/VLM safety & security. I’ve helped identify over 30 bugs in fastjson2, a popular open source JSON library by Alibaba.
