I am currently an associate professor in the Department of e-Commerce, School of Management, Guangdong University of Foreign Studies, and also a research fellow in the Institute of Bussiness Intelligence and Knowledge Discovery, Guangdong University of Foreign Studies. I got my Ph.D. degree from the State Key Laboratory of Computer Science, Institute of Software, Chinese Academy of Sciences in 2009. From then on, I worked for Guangdong University of Foreign Studies as a teacher.

Research Interests
