I am a Ph.D. candidate in ANSR Lab, supervised by Chair Professor John C.S. Lui (ACM/IEEE Fellow, Fellow of HKAES) at the Department of Computer Science & Engineering, The Chinese University of Hong Kong (CUHK). Before that, I obtained my honor bachelor degree (Advanced Class, GPA: 3.95/4.0) from the Department of Electronics and Information Engineering at Huazhong University of Science and Technology (HUST).

Research

My research centers on “intelligent decision-making”. By developing theoretically grounded frameworks, such as reinforcement learning, online learning, and multi-armed bandits, I strive to design efficient, scalable, and trustworthy algorithms for optimal decision-making.

I always welcome discussions and collaborations. Feel free to reach out via email: “xiangxdai0 [at] gmail.com” (recommended) or “xxdai23 [at] cse.cuhk.edu.hk”.
