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. I earned both my Bachelor and Master degree from Fudan University, under the mentorship of Prof. Zhe Zhou. Additionally, I was a member of Fudan’s CTF team ******(Sixstars).
