My research has focussed on real-time networked multimedia, congestion control for multimedia systems, next-generation Internet routing, and on the use of high-level languages for low-level protocol implementation. I favour systems research, often done in collaboration with industry, demonstrating feasibility through prototype implementations where possible, and driving results into the standards process to encourage broad deployment.

I'm grateful for support from the UK EPSRC, the European Commission, the US National Science Foundation, DARPA, SICSA, Cisco, Ericsson, Huawei, Rakuten Mobile, and others, for funding my students and other research activities.
