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, where I worked with Prof. Hongbo Jiang. I also interned at Shenzhen Institutes of Advanced Technology (SIAT), Chinese Academy of Sciences, where I had collaborations with Prof. Guang Tan.

My current research interests include data mining, data analytics in online social networks, and online learning algorithms. I have also been interested in designing distributed routing protocols for wireless sensor networks in IoT (Internet of Things).
