About me

I am a third-year Ph.D student at Peking University, where I am very fortunate to be advised by Prof. Qingni Shen and work closely with Zhi Zhang. I am also a visting Ph.D student at National University of Singapore since October 2024, advised and funded by Prof. Trevor E. Carlson. Previously, I obtained my bachelor’s degree in Information Security from Hunan University. For more details, you can refer to my CV.

My research interests are in system security and computer architecture. In particular, I focus on re-evaluating the rationale behind certain hardware designs, and uncovering new side-channel leakages to offer designers insights for building more secure systems.
