I am a researcher (Univ.Ass. Dr.techn.) at Research Group Cartography, Vienna University of Technology, Austria. I received a Ph.D. degree from the same university in 2013, focusing on context-aware recommendations in Location-based Services (LBS). My current research continues within the fields of LBS, context-awareness, and geotagged social data analysis. Before coming to Vienna, I studied Computer Science in South China Normal University.
