My research interests are on network transport protocols, with a particular focus on transport protocols for real-time and interactive multimedia, and on network protocol design, implementation, and specification. My current research is into post-Sockets APIs and transport services, the implications of QUIC on real-time applications and network operations, and improving the way we specify network protocol standards.
I'm a long-time participant in the Internet Engineering Task Force (IETF). I co-chair the RTP Media Congestion Avoidance Techniques working group, and was previously co-chair of the Audio/Video Transport and Multiparty Multimedia Session Control working groups. I played a key role in helping to develop globally deployed standard multimedia transport and signalling protocols such as RTP, SDP, and the WebRTC media transport layer.
I received my BEng in Electronic Engineering in 1992, and my DPhil in 1996, both from the Department of Electronics at the University of York. I'm a fellow of the Higher Education Academy, a senior member of the IEEE, and a member of the ACM and IET.
