I'm Ruijie (pronounced like Ray Jey), an incoming tenure-track faculty of CISPA Helmholtz Center for Information Security. I am finishing my Ph.D. at School of Computing, National University of Singapore (NUS), advised by Professor Abhik Roychoudhury.

My research interests lie in software security and software testing. My recent research primarily focuses on automated validation of distributed, concurrent, and stateful software systems. I leverage and also advance techniques such as fuzz testing, model checking, program analysis, and AI-driven testing to improve the security and reliability of software systems.
