Hi, I’m Junquan Deng (邓浚泉, pronounced like “Joon-chwan Deng”). I am a master’s student at the Institute of Software, Chinese Academy of Sciences. I am advised by Prof. Purui Su and Assoc. Prof. Xiangkun Jia. My research focuses on software and system security, particularly vulnerability detection. I use fuzzing, program analysis, and LLMs to identify vulnerabilities in modern software, especially in emerging generative systems.
