Research Interests

Jun Li is interested in computer networking, Internet of things, and cyber security and privacy. 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.
