About

I am a post-doc research fellow working with Prof. John C.S. Lui in Department of Computer Science and Engineering at The Chinese University of Hong Kong. I received my Ph.D. degree in Computer Science supervised by Prof. John C.S. Lui at The Chinese University of Hong Kong in 2019.

My 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).
