Principal Research Associate in the Communications and Information Systems Group, Department of Electronic and Electrical Engineering, University College London. I have a BSc in Electronic, Computer and Systems Engineering from Loughborough University and a PhD in Electronic and Electrical Engineering from UCL.

Before joining UCL I was a Systems Design Engineer at GEC-Plessey Telecommunications (which became Marconi Communications and is now part of Ericsson). In 1993, I joined the Foundation for Research and Technology, Institute of Computer Science, Greece as a Research Associate in Telecommunications where worked on performance optimisation of multi-service networks.

I have published over 50 papers and I was the editor and co-author of "Integrated Communications Management of Broadband Networks" (Crete University Press, 1997). I have had a significant involvement in EU research programmes RACE, ACTS, IST and ICT projects (NEMESYS, ICM, VITAL, REFORM, MIAMI, TEQUILA, MESCAL, AGAVE, ENVISION and FUSION) and was co-investigator of the EPSRC-funded PeerLive project on streaming live video over p2p networks. I am currently the project manager of the EU FP7 FUSION project investigating new networking architectures with native support for provisioning, discovery and execution of service components distributed over the Internet.
