Jianjun Chen is a postdoc at the University of Chicago supervised by Prof. Nick Feamster. Before that, he was a postdoc advised by Prof. Vern Paxson at International Computer Science Institute, an independent non-profit research institute affiliated with UC Berkeley. He was a Ph.D. student at Tsinghua University advised by Prof. Haixin Duan.
His research interest focus on network security, protocol security, and system security. His past research has discovered a series of high-impact security vulnerabilities in widely-used Internet protocols and systems. Those efforts have been recognized by the academic community, winning two Distinguished Paper Awards (NDSS and USENIX security) on the top-tier security conferences, and led to many real-world security responses, such as patches in popular HTTP implementations (e.g., Squid , Chrome , Firefox ), security advisories by industrial companies (e.g., Akamai , Cloudflare , Apple ), web standard change , and a new IETF RFC .
I am serving as an reviewer for IEEE/ACM Transactions on Networking(ToN).
