About Me

Welcom to my homepage!

My name is Yizhe Shi, a Ph.D. candidate at the College of Computer Science and Artificial Intelligence, Fudan University. I am a student of the System Software and Security Laboratory, advised by Prof. Zhemin Yang and Prof. Min Yang.

My research interests focus on Mobile Security, especially within the App-in-App ecosystem (e.g., mini-apps and super-apps), Program Analysis and LLM/Agent Security. I am interested in understanding emerging security and privacy risks in complex mobile and LLM-augmented ecosystems, and in building automated, LLM-assisted techniques to detect vulnerabilities and malicious behaviors at scale.
