Update (2016/08): I have graduated and joined Twitter's Recommendations team.
I was a PhD student School of Computing Science, Simon Fraser University, BC, Canada. My thesis supervisor is Professor Martin Ester. Before I moved to Canada, I received my B.S. degree from Special Class for the Gifted Young (SCGY), University of Science and Technology of China (USTC) in 2009, and M.S. degree from National Laboratory of Pattern Recognition (NLPR), Institute of Automation, Chinese Academy of Sciences in 2012, under the supervision of Professor Qing Yang. During my PhD, I interned once at @WalmartLabs and twice at Dato (formerly GraphLab) Inc..
I am broadly interested in data mining, machine learning, recommender systems and social network analysis. My PhD thesis is Towards Better User Preference Learning for Recommender Systems .
