Jianjun Chen is a postdoc supervised 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 focuses on studying real-world systems to understand their security challenges and develop mitigation solutions. He worked in the areas of CDN security, HTTP implementations, web browsers, and email systems. His previous research was published on top-tier security conferences (NDSS, ACM CCS, USENIX Security), and led to some real-world security pushes, 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).
