The Chinese University of Hong Kong


I am currently a Ph.D. student in Department of Computer Science and Engineering at The Chinese University of Hong Kong. My supervisor is Prof. John C.S. Lui. I received the bachelor's degree and master's degree, both with the highest honor in Department of Electronics and Information Engineering at Huazhong University of Science and Technology in China.

My current research interests include data mining, data analytics, and designing reinforcement learning algorithms for various kinds of applications, such as web recommendation systems, computer networks, and online social networks. I have also been interested in designing distributed routing protocols for wireless sensor networks in IoT (Internet of Things).
