Biography [CV pdf]

I am currently a postdoc at Department of Electrical Engineering and Computer Science, University of Liège (ULG), Belgium. I received my B.S. in 1999 and M.S. in 2002, both from Department of Computer Science, Guangxi University, China. I joined Research Unit of Networking (RUN) at ULG, led by Professor Guy Leduc, in 2007, and defended my PhD thesis in January 2013. Before, I had worked as a software engineer in a small computer company in Beijing, China.

My main research interests are the applications of machine learning techniques to computer networking problems, specifically the prediction of end-to-end network performance in large-scale networks.
