Hi, I'm Junquan Deng
How to pronounce ζ΅šζ³‰ ι‚“
Joon-chwan Deng

I am currently a research intern at Microsoft, mentored by Dr. Zhiyu Fan and Dr. Pengfei Gao. I will be joining the University of Waterloo as a PhD candidate. Previously, I earned my master’s degree at the Institute of Software, Chinese Academy of Sciences, advised by Prof. Purui Su.

My research focuses on the intersection of software security and generative AI. I use fuzzing, program analysis, and LLMs to identify vulnerabilities in modern software. Recently, I have also begun treating generative systems themselves as a novel form of software, investigating the inherent defects within them.
