Hello and welcome! My name is Jiayi Zhang (he/him). I am a PhD candidate at HKU, advised by Chenxiong Qian. I earned an MSc(Comp) in Computer Science with distinction from HKU in 2023. I received a dual BSc(Eng)(Hons.) and B.M. degree, graduating with First Class Honours in E-Commerce Engineering with Law from BUPT and QMUL in 2022. My research interests include ML for game security and anti-cheat&cheat in FPS games.
Iβm also an avid Overwatch player. If you play Overwatch, feel free to duo with me (CN or Asia server).
