Welcome to my webpage. I am a Professor at the School of Computer Science and Electronic Engineering (CSEE) at the University of Essex, Colchester, United Kingdom and the CSEE Director of Research. Before that, I was a senior researcher in the Signal Processing Laboratory (LTS4) at the Ecole Polytechnique Federale de Lausanne (EPFL), Lausanne, Switzerland and the Communication and Distributed Systems Laboratory (CDS) at the University of Bern, Bern, Switzerland. I received my Diploma (MSc equivalent) and PhD degrees from the Electrical and Computer Engineering Department of the Aristotle University of Thessaloniki, Thessaloniki, Greece. 

I was awarded the highly esteemed Ambizione career award from the Swiss National Science Foundation (SNSF) in 2008 and 2011 for carrying out research on low computational complexity network coding for collaborative video streaming. I have been PI and co-I for a number of SNSF, Hassler Foundation, EC, and InnovateUK-funded projects. I regularly serve as a member of technical program committees of international conferences. I am an elected member of the IEEE MMSP Technical Committee (MMSP - TC) for the period 2019 - 2024. I am currently a TPC chair of ICME'25 and MMSP'24. I was the co-chair of the Doctoral Symposium at ICIP’18, Vice-Program Chair of CIT'18, the Awards co-chair of MMSP’17, and the Publications Chair of the IEEE workshop Packet Video 2012 and 2016. 

My research interests include machine learning for communications, multimedia communications, semantic communications, network coding, information-centric networking, networking, joint source and channel coding, device-to-device communication, signal processing and sensor networks.

I am a Senior Member of the IEEE, a Fellow of the Higher Education Academy, and a Peer Review College Member of the Engineering and Physical Sciences Research Council (EPSRC).  

Prospective PhD students interested in pursuing research in network coding, multimedia communications, networking, and multimedia sensor networks are encouraged to contact me by e-mail.
