About Me

• I am currently a PhD candidate at the Department of Computer Science at Purdue University, advised by Prof. Xiangyu Zhang. Before that, I obtained my bachelor’s degree in Computer Science and Technology from Zhejiang University in 2019.

• My research interests are program analysis and software testing. I specialize in bug detection and have found hundreds of vulnerabilities in various applications, including PDF readers, network protocol libraries, and 5G systems. I am also interested in applying LLMs in software engineering tasks.
