I am a PHD student at Purdue University working with Prof. Dave Tian since May 2023. My research interests span computer security and systems. Recently, I have been focusing on topics related to GPUs, Rowhammer, and side-channel attacks. From Aug 2025 to Mar 2026, I was a visiting student at Clemson University, where I worked with Prof. Zhenkai Zhang on GPU Rowhammer, including GeForge. Before PHD, I earned both my Bachelor and Master degree from Fudan University, working with Prof. Zhe Zhou. Additionally, I was a member of Fudan’s CTF team ******(Sixstars).
