I'm currently an Associate Professor at the Department of Computer and Information Science with the State Key Laboratory of Internet of Things for Smart City at the University of Macau. Prior to that, I was a senior researcher in the eXascale Infolab at the University of Fribourg, Switzerland from 2015 to 2020. I received my Ph.D. (with highest honors) in Computer Science from Institut Mines-Télécom/Télécom SudParis and Université Pierre et Marie Curie, Paris 6 in Jan. 2015, under the supervision of Prof. Daqing Zhang. In June 2015, My Ph.D. thesis won the CNRS Samovar Doctorate Award ("Prix Doctorant CNRS Samovar/Télécom SudParis") and Institut Mines-Télécom Press Mention. I'm also a recipient of the "2014 Chinese Government Award for Outstanding Self-financed (non-government sponsored) Students Abroad".
I'm broadly interested in designing novel data mining and machine learning techniques to efficiently discover knowledge and get insights from Big Data, and also in building practical systems to tackle real-world problems. My research interests lie primarily on Ubiquitous Big Data Analytics, Social Network Analysis, Predictive Modelling, Data Sketching, and Data Privacy.
