I’m Peiran Wang (王沛然 in Chinese, you can speak as “Pay-than, Wang”), a CS PhD student in UCLA
. I am currently interested in general AI Security (including LLM security, privacy, etc. Especially system security for LLM recently), Machine Learning System (MLSys), usable security, fraud detection and program analysis, etc. I graduated from Sichuan University
in Cybersecurity Talented Class in 2022 (18/172). During my undergraduate, I got National Scholarship (3/172), and got GPA of 3.92 (rank 2/172). I’m currently a CS PhD student in UCLA, under the supervision of Prof. Yuan Tian.
