Profiles:

Currently I am visiting University of Cambridge Computer Laboratory Systems Research Group as a research associate (2013). Before that, I was a PostDoc in the University of Helsinki, and work in the area of content networks (2011-212). In addition, I ever worked in the Hong University of Science and Technology (HKUST), and received a PhD degree in the Chinese University of  Hong Kong (CUHK) from 2005 to 2009.

Research Interests
