Biography

Prof. Polyzos received his Diploma in Electrical Engineering from the National Technical University of Athens, Greece and his M.A.Sc. in Electrical Engineering and Ph.D. in Computer Science from the University of Toronto, Canada. He then joined the University of California, San Diego (UCSD), where he was Professor of Computer Science and Engineering, co-director of the Computer Systems Laboratory, member of the Steering Committee of the UCSD Center for Wireless Communications, and Senior Fellow of the San Diego Supercomputer Center. He then moved to the Athens University of Economics and Business (AUEB) as Professor of Computer Science, where he founded and directed the Mobile Multimedia Laboratory and was Director of the Graduate Program in Computer Science.

Prof. Polyzos has advised or co-advised 16 Ph.D. students and supervised many graduate and undergraduate theses and projects. He has published more than 300 refereed papers and there are more than 12000 citations to his publications (H-index 48). His current research interests include Security and Privacy, Distributed Systems and Blockchains, Internet Architecture and Protocols, Internet-of-Things, Smart Grids, Smart Cities, Supply Chains Transparency and Traceability, Digital Identity, Performance Analysis of Computer and Communications Systems

Dr. Polyzos has been Principal Investigator or has participated in many research projects, with public and/or industrial funding, including by the US National Science Foundation, Digital Equipment Corporation, National Semiconductor Corporation, Hitachi, Microsoft Research, the European Commission, the European Space Agency, and the Greek government. Under his leadership the AUEB/MMlab has participated in a series of Research projects funded by the European Commission (FP7 PSIRP, FP7 PURSUIT and H2020 POINT) that developed Publish-Subscribe Internetworking, an Information-Centric Networking (ICN) architecture. FP7 project PURSUIT received the Future Internet Award in 2013. He also led MMlab’s participation in H2020 projects SOFIE (Secure Open Federation for Internet Everywhere), which developed technologies for enabling the open interoperation of IoT “silos” and 4th Generation business platforms and InterConnect (Interoperable Solutions Connecting Smart Homes, Buildings and Grids), which contributed to the democratization of efficient energy management, through a flexible and interoperable ecosystem where demand side flexibility can be soundly integrated with effective benefits to end-users.

Dr. Polyzos has served on the editorial board of IEEE Transactions on Mobile Computing, Journal of Reliable Intelligent Environments, Wireless Communications and Mobile Computing, and has served as guest editor for: IEEE Personal Communications, Mobile Networks and Applications, IEEE Journal on Selected Areas in Communications, and Computer Networks and on the Program Committees of many conferences and workshops. He has also chaired the Steering Committee of the ACM SIGCOMM conference on Information-Centric Networking and is now on the Steering Committee of the Wireless and Mobile Networking Conference (IFIP TC6 WG 6.8).
