🧐 About Me

I am now a PhD student at Beihang University (BUAA), School of Cyber Science and Technology, supervised by Dr. Yanqing Yao. I am also very fortunate to closely work with Prof. Di Wang, who directs the PRADA Lab at KAUST. Previously, I received my B.Eng. degree at Xidian University (XDU), School of Cyber Engineering, under supervision of Dr. Shanfeng Wang and Dr. Yanqing Yao in June 2023.

My research interests include Machine Unlearning and Differential Privacy-based Privacy Preservation for federated learning. In the area of machine unlearning, my work primarily revolves around efficient provable federated unlearning and efficient verifiable LLM unlearning. In the field of differential privacy-based privacy preservation for federated learning, I have recently been focusing on the design of high-availability personalized differential privacy aggregation algorithms to enhance federated learning systems.

✨ Miscellaneous

Apart from academic pursuits, I enjoy a wide range of sports such as swimming, cycling, badminton and ping-pong. Additionally, I am a passionate photographer, always seeking to capture the beauty of the world through my lens. One of my special hobbies is that I love all things about deduction and suspense, especially I am a fan of the anime 名探偵コナン (Detective Conan, 名侦探柯南) and the TV series Detective Dee (神探狄仁杰)!
