Welcome to Zhen Xiang’s homepage!

I am a postdoc affiliated with the Secure Learning Lab (SLL) led by Prof Bo Li at the Department of Computer Science, University of Illinois Urbana-Champaign. I received my B.E. in Electronics and Computer Engineering from Hong Kong University of Science and Technology in 2014, my M.S. in Electrical Engineering from University of Pennsylvania, and my Ph.D. in Electrical Engineering from Pennsylvania State University supervised by Prof David J. Miller and Prof George Kesidis in 2022.

I work on trustworthy machine learning, with the main focus on backdoor attacks and defenses. My long-term goal is to develop theory-based defense approaches and security standards for safety-sensitive applications.

I will be on the job market 2023/2024!
