Summary
Mark Handley is a Professor of Networked Systems at UCL and a Member of Technical Staff at OpenAI, blending deep academic research with applied engineering in networking and AI. He has co-authored some 30 RFCs—spanning SIP, SDP, multicast routing, DCCP and TFRC—and helped pioneer Multipath TCP, shaping how real-time and streaming systems behave on the Internet. With over 60 papers and more than 22,000 citations, his work ranges from congestion control and routing to one of the original Distributed Hash Table papers, reflecting both theoretical depth and practical impact. He has served on IETF and IAB leadership bodies and chaired influential working and research groups, bringing protocol standardization experience to product-scale problems. Prior industry roles at Broadcom and research stints at ICSI and ISI complement his long-running UCL appointment, giving him a rare cross-section of standards, research and product engineering. An often overlooked thread of his career is consistently translating protocol-level insight into deployable systems used in telecom and IPTV infrastructures.
