Hi, I'm Junquan Deng (邓浚泉, pronounced like "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 CISPA Helmholtz Center for Information Security as a PhD candidate, advised by Dr. Ruijie Meng. Previously, I earned my master’s degree at the Institute of Software, Chinese Academy of Sciences, advised by Prof. Purui Su and Assoc. Prof. Xiangkun Jia.
My research focuses on improving the reliability and quality of modern software systems. I develop automated testing and analysis techniques to make software more dependable.
