George Zervas is an Associate Professor of optical networked systems in the Department of Electrical and Electronic Engineering at University College London. He received his MEng degree in Electronic and Telecommunication Systems Engineering with distinction and PhD degree in optical networks from University of Essex in 2003 and 2009 respectively. Following this, George held the positions of Research Associate and subsequently Research Fellow and Lecturer as a member of High Performance Networks group at University of Essex where he investigated multi-granular optical switching.

In 2012-16 he was appointed Lecturer and Senior Lecturer at University of Bristol where he led the research activities on optical networked systems with emphasis on optical switching, flexible and space division multiplexed networking, programmable electronic and optical hardware as well as data centre systems. Also, he held the position of visiting Associate Professor at Keio University, Tokyo. He is the recipient of the prestigious 5-year Fellowship from the Engineering and Physical Sciences Research Council (EPSRC) within Information and Communications Technology in the U.K.

He is the author and co-author of over 275 international peer-reviewed journal and conference papers including numerous prestigious post-deadline papers at ECOC/OFC as well as best paper awards. He has also given over 40 invited talks at several international conferences. His research interests lie in the fields of optical networked systems for data centres, high performance computing and telecoms with particular focus on optical switched interconnects, topologies, control, architectures and compute & network co-design.

George has been involved in several current and past EC and EPSRC and industrial funded projects as principal and co- investigator. He has been acting as a TPC member on international conferences such as OFC, ICC, Globecom, ONDM, ACP, among others. He is associate editor of IEEE Networking Letters and has been serving as guest associate editor on IEEE JOCN. Dr. Zervas has been involved in Internet Engineering Task Force (IETF) and Open Grid Forum (OGF) standardization fora. George is a member of EPSRC Peer Review Associate College and has served as expert reviewer in other non-UK national funding bodies.
