    I am a project officer at the Data-Intensive Scalable Computing Lab, School of Computer Engineering, Nanyang Technological University. I did my PhD study in School of Computer Engineering, Nanyang Technological University (NTU) from August 2010 to September 2014. My supervisor is Asst. Prof. Gao CONG, and my co-supervisor is Prof. Nadia MAGNENAT-THALMANN. Prior to joining NTU, I obtained my Bachelor degree from School of Computer, Beijing University of Posts and Telecommunications, China, in June 2010. My research interests include recommender systems in social media and spatiotemporal mobility modeling for users. I also did some research on text mining in community-based question answering services and microblogs. PUBLICATIONS A tri-role topic model for domain-specific question answering.
