Yu Sun

Ph.D. Candidate

Department of Computing and Information Systems

The University of Melbourne

I am currently a fourth-year Ph.D. student at the University of Melbourne. Before commencing my Ph.D. in 2013, I worked for seven months at Nanyang Technological University. I obtained my bachelor's degree in Computer Science from Renmin University of China in 2012. Last year, I visited the Social Computing Group of Microsoft Research Asia.

My research interests include context-aware recommendation, spatial/temporal data management and visualization.
