I am a PhD student in Database group, advised by Prof. Nikos Mamoulis. My current research interests lie in building machine learning infrastructure to support scalable and effective recommender systems. I was with Database group at the University of Maryland, College Park, advised by Prof. Amol Deshpande from Aug 2015 to Jan 2016.
