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).

My research interests are broadly in the area of networking, with a special focus on future Internet architectures, edge-/fog-computing, resource management, caching and congestion control. More recently, we're investigating issues related to decentralised and distributed Internet architecture, distributed governance and its applicability to edge- and fog-computing, through Distributed Ledger Technology and Blockchains.
