I am a University Professor of Computer Science at the
Institute of
Computer Science,
University of Goettingen
and leading the Computer
Networks (NET) Research Group. I received my Ph.D. (2000) degree in Computer
Science from Tsinghua University,
Beijing, China, under the supervision of Professor
Yaoxue Zhang (Fellow of
Chinese Academy of Engineering, elected in 2007). Prior to joining Goettingen, I worked with Prof. Dr.-Ing. Adam Wolisz
as a research fellow at the
Telecommunications Networks (TKN) group,
Technical University Berlin until
September 2002. Between 2003
and 2005 I also served in the
European Telecommunications Standards Institute
(ETSI) as an Expert in
Specialist Task Forces
in Internet Protocol (Version 6) Testing.
I was/am a visiting scholar at the University of Cambridge (host: Prof. Jon
Crowcroft) in 2005 and 2007, a DAAD visiting professor at Columbia University
(host: Prof. Henning Schulzrinne) in 2008
and 2009, and currently a Fulbright Scholar Visiting Professor at UCLA (hosts:
Prof. Lixia Zhang and Prof.
Mario Gerla). Since October 2008 I serve as the
secretary of the Technical Committee on Computer
Communications (TCCC), IEEE Communications Society (ComSoc).
I am a senior member of IEEE, a member of
ACM and a member of
GI.
Research:
My research interests include the architecture, technology and protocols of
Internet-based communication systems; an overview of my work so far in these
areas is briefly described in my curriculum vitae or research
statement. I am currently involved in several collaborative
research projects, addressing various aspects on the
design, validation, implementation, performance evaluation and analysis of new network
and distributed systems architectures, protocols and services, especially signaling and QoS,
transport protocol performance, overlay and virtualization, network security and
resilience, system support for multimedia systems and mobile networking,
including online social networks.
Projects:
My research team has been sponsored by European Commission, State Lower Saxony,
Siemens, Nokia Siemens Networks, German Telecom, ETSI, Panasonic, Huawei, as
well as German Academic Exchange Service (DAAD), US Department of State, and
Chinese Scholarship Council (CSC). In addition, we work in close collaborations
with many national and international institutions and industry partners.
