About me

I am currently a second-year Ph.D. student in the Department of Computer Science & Engineering at The Chinese University of Hong Kong. I am a member of Advanced Networking and System Research Laboratory (ANSRLab) and my supervisor is Prof. John C.S. Lui. I receive my bachelor’s degree with honered rank(top 5% students) in the Department of Computer Science and Technology at University of Science and Technology of China in 2017.

My major interests are Machine Learning and Data Mining techiques as well as Statistic Modeling. Among them, online learning and reinforcement learning are my recent research focus. In addiction, I am interested in network science, including research in social networks.

My CV is here/这里

In my spare time, I love playing basketball and I am a big fan of KING JAMES(that is why I choose “James” as my English name). Music is also my favorite. I like listening to all kinds of music and can play a little guitar, ukelele and piano.
