Professor Christos Politis

About

I am Professor (Chair) of Digital Technologies at Kingston University London, School of Computer Science (CS). There I am the Director of the Digital Information Research Centre (DIRC) with a staff of about 23 academics, 15 postdoctoral researchers and over 40 PhD students, making it one of the largest in the field in the UK. Upon joining Kingston University in 2007, I co-founded and led a research group on Wireless Multimedia & Networking (WMN). I teach modules on wireless systems, networks and protocols. Prior to this post, I worked for Ofcom, the UK Regulator and Competition Authority, as a Senior Research Manager. While at the University of Surrey, I was a PostDoc working on virtual distributed testbeds in the Centre for Communication Systems (now the 6G Innovation Centre). This was preceded by placements with Intracom-Telecom SA and Maroussi 2004 SA in Athens, Greece. I have managed to raise sustained funding from the EU and UK research and technology frameworks under the ICT and Security programmes (FP5/6/7, H2020, EPSRC and Innovate UK). I hold two patents and have published over 200 papers in international journals and conferences and chapters in eleven books. In parallel to my academic career, I advise and consult for several governmental and commercial organisations on their research programmes/ agendas and portfolios in EU, UK, Canada, Greece, Qatar, China, Malaysia to mention a few. I hold a PhD and MSc from the University of Surrey, UK and a BEng from the University of Athens, Greece, all in Electrical and Electronic Engineering. I am senior member of the IEEE and UK chartered engineer.
