Bio

I am a PhD student in Database group, advised by Prof. Nikos Mamoulis. My current research interests lie in recommender systems and knowledge graph.


Since Sep 2017, I am doing an internship in Systems and Machine Learning group, NEC Laboratories Europe. I was with Prof. Amol Deshpande at University of Maryland, College Park from Aug 2015 to Jan 2016 and Prof. Rainer Gemulla at University of Mannheim from Apr 2017 to Aug 2017.
