I am an EPSRC Fellow (2015-2020) and Lecturer with the E&EE Dept. at UCL, London. I have been at UCL since 2010, working on several EU and EPSRC projects. Before that, I was with the University of Surrey, CCSR (2008-2010). I graduated from Democritus University of Thrace, Greece, where I obtained both a Diploma in Engineering and a PhD.

My research interests are broadly in the area of networking, with a special focus on future Internet architectures, resource management, caching and congestion control.
