Zheng Li

Professor at Shandong University

I am a professor at School of Cyber Science and Technology, Shandong University.

Previously, I was a postdoc at CISPA Helmholtz Center for Information Security, supervised by Dr. Yang Zhang. In Oct 2023, I obtained my Ph.D. from CISPA Helmholtz Center for Information Security, supervised by Dr. Yang Zhang. I received my bachelor (2017) and master (2020) degrees from Shandong University, supervised by Prof. Shanqing Guo.

Research Interests

My research centers on Trustworthy Machine Learning (Privacy, Security, and Safety), especially analyzing machine learning model vulnerabilities, including privacy attacks (MIA and AIA), backdoors, and data poison attacks. Additionally, I work on technical solutions against unethical AI systems.

I am looking for motivated PhD/master students (25 Fall) and research assistants to join my group. If you are interested, please write me an email (zheng.li@sdu.edu.cn).
