I am a full-time research assistant of Computer Networks Group, University of Goettingen. My supervisor is Prof. Dr. Xiaoming Fu.

I received my B.S. and M.E. degrees in Computer Science from Nanjing University, China. My Master's advisor is Prof. Sanglu Lu, Prof. Baoliu Ye, and Prof. Wenzhong Li. In 2007, I was selected for graduate study exempted from the graduate school entrance exam at Nanjing University. In 2010, I was awarded a highly selective fellowship (LiSUM scholarship) from the Chinese National Commitee for Education for graduate exchanging in Europe, and studied at University of Goettingen.

My current research interests are in networking and distributed systems, in particular, online social networking, multimedia communications, overlay/peer-to-peer networking, service-oriented computing.
