Jun Li is a Professor at the University of Oregon, where he also directs the Network & Security Research Laboratory in the Department of Computer and Information Science and serves as the Founding Director of the interdisciplinary Center for Cyber Security and Privacy.  Jun has authored a research book on disseminating security updates over the Internet and more than 70 peer-reviewed research papers.  He received his Ph.D. from UCLA in 2002 (with Outstanding Doctor of Philosophy honor), M.E. from Chinese Academy of Sciences in 1995 (with a Presidential Scholarship), and B.S. from Peking University in 1992, all in computer science.  In 2011 he held a "Catedra de Excelencia" (Chair of Excellence) at the Carlos III University of Madrid, Spain, and was a visiting researcher at the IMDEA Networks Institute in Spain.

A senior member of both ACM and IEEE, Jun has served on US National Science Foundation research panels and 70 international technical program committees, including chairing IWQoS 2015, GI 2014, NPSec 2014, Globecom CISS 2014, and NPSec 2013.  Additionally, he has been serving on the editorial boards of IEEE Transactions on Dependable and Secure Computing and Elsevier Computer Networks.  Jun also organizes the annual Oregon Cyber Security Day.

Research Interests

Jun Li is interested in networking, distributed systems, and their security. He studies not only the functioning and performance of fundamental networking functions (e.g., routing and naming), various networking paradigms (e.g., software-defined networking, Internet of Things, data center networking, peer-to-peer networking), and popular applications (e.g., online social networking), but also their problems in, or usage for, security and privacy.  He studies both direct countermeasures against network security attacks (including Internet worms, phishing, botnets, and Sybil attacks) and fundamental security issues and solutions at the network architecture and protocol level (such as DDoS defense, Internet routing security, and DNS security).
He currently serves as the principal investigator on a 2015-2018 1.38-million grant researching the defense against distributed denial-of-service (DDoS) attacks on the Internet. Dubbed DrawBridge, this research project leverages software-defined networking (SDN) to enable Internet service providers to more effectively filter DDoS traffic.  In collaboration with University of Arkansas and UNCC, he is also the principal investigator on a 2016-2020 1.2-million NSF grant to study fraud and attack detection within online social networks.  Jun Li also works with an interdisciplinary team to study Internet privacy, thanks to the Incubating Interdisciplinary Initiatives (I3) award from the Office of Research and Innovation of the University of Oregon.  Over the past decade he has been continuously funded by the National Science Foundation as a principal investigator on various other projects in cyber security and networking, including the NSF CAREER award in 2007.
