SUMMARY
Dr. Ioannis Tomkos, has the rank of tenured Full Professor at Athens Information Technology Center since September 2005 and serves as Associate Dean since June 2004. He joined AIT as a tenured Associate Professor in July 2002. In December 2002, he became an Adjunct Faculty at the Information Networking Institute of Carnegie-Mellon University, PA, USA. While at AIT, he initiated and co-developed new graduate programs (e.g. the M.Sc. on Management of Business Innovation and Technology) and has played an important documented role in AIT’s development. At AIT he founded and serves as the Head of the “High Speed Networks and Optical Communication (NOC)” Research Group (currently consisting of 10 researchers), which performs advanced research related with its areas of interest. The NOC group participates in a number of EU funded research projects (FP7 ICT-1 STREP DICONET, FP7 ICT-1 STREP SARDANA, FP7 ICT-1 NoE BONE, FP7 ICT-2 STREP APACHE, FP7 ICT-2 NoE EUROFOS, EU FP6 IST-3 SSA BReATH, EU FP6 IST-4 STREP TRIUMPH, EU FP6 IST-4 NoE e-Photon/ONE2, COST 291 TDON) in all of which Dr. Tomkos is representing AIT as Principal Investigator. In all these projects Dr. Tomkos also has a consortium-wide leading role: he is Chairman of the EU COST 291 project, Project Leader of the EU ICT STREP project DICONET, Technical Manager of the EU IST STREP project TRIUMPH, Leader of two Joint Projects in the framework of BONE NoE project, Leader of a Joint Project in the framework of e-Photon/ONE2 EU NoE project, co-Leader of a work-package in the framework of the EUROFOS NoE project, while he serves as Steering Board member or/and WP leader in other projects. The NOC group participates also in collaborative research and consulting projects with high-tech industries. The level of funding raised by AIT due to the research activities of the NOC group exceeds 2.3 Million Euros. In 2002, he also founded the “Optical Networking” laboratory at AIT. His current research interests cover technical aspects of telecommunication systems and networks and technoeconomic and regulation/policy aspects of broadband networks and services. On these topics, he has developed the syllabus and teaching material of several graduate and executive/professional training courses, including those on “Optical Networks”, “Optical Communications”, “Telecom Management”, “Technoeconomics for value analysis”, “Policies and regulations of the ICT industry”, “TPC/IP networking” etc. Dr. Tomkos has acted as consultant for high-tech ICT companies and his work (mainly on technoeconomic studies and business planning for broadband networks and FTTx deployments) has resulted in measurable benefits for his customers (e.g. he was responsible for the preparation of the business plan and the associated techno-economic study that the Greek telecom operator HOL submitted to the Greek Government and as a result it was awarded a 43ME subsidization fund for the deployment of a nation-wide broadband network).
His professional career started in 1996, when he joined the University of Athens, Greece and participated in several national and European research projects as a Research Fellow. His work there was related with WDM technologies for optical networks and with systems (e.g. xDSL, HFC) for broadband access networks. In January 2000, he joined the Photonics Research and Test Center of Corning Inc. as a Senior Research Scientist. His research focused in theoretical and experimental studies related with WDM optical networks. He studied extensively the performance and design issues of metropolitan/regional area optical networks and led successfully several projects. He was then subsequently involved in studies related with transport performance and technology trends in ultra-long-haul optical networks. At Corning Inc. he demonstrated customer-driven and results-oriented spirit contributing to several commercial success stories. In June 2002 he was elected a Faculty member at the Computer Engineering Department of University of Patras, Greece. In July 2002 he joined AIT.
Dr. Tomkos has received the prestigious title of “Distinguished Lecturer” of IEEE Communications Society for the topic of transparent optical networking (2006-2007). Together with his colleagues and students he has authored over 85 peer-reviewed articles published in international scientific journals/magazines/books (about 70 archival journal articles through the ISI Web of Science; more than 40 IEEE sponsored) and about 180 presentations at conferences/workshops and other events (over 135 archival publications in conference proceedings; over 90 archival through IEEE Xplore). He has co-edited a Springer book entitled “Optical Network Design and Modelling”, a Springer book entitled “Towards Digital Optical networks” and he has also authored a book chapter in the Wiley Encyclopedia of “Telecommunications and Signal Processing”, related with “Metropolitan area broadband networks”. He has also published a large number of articles in business/technology magazines about technical, technoeconomic and regulation/policy aspects of telecom broadband networks. He has received many invitations from conference technical program committees (most notably twice from OFC) to present his research results as Plenary/Invited/Tutorial Speaker or to coordinate a set of presentations as Session Chair or Panel Moderator. His published articles have received more than 700 citations. He holds 2 patents and has several patent applications pending. He is a member of the “Photonics21” Technology Platform that prepared the EU Strategic Research Agenda in photonics. He is also among the main contributors on optical networking to the “Future Internet: research agenda. In 1991, 1992 and 1993 he received Educational Scholarships by the Hellenic Institute of National Scholarships. In 1998 he received a Grant and also the "Best Paper" Award from IEEE-LEOS. In 1999 he received a Scholarship from SPIE. In 2000 he was awarded by Corning Inc. for his contributions in the development of a new optical fiber. In 2002, he received the "2001 Corning Research Outstanding Publication Award".
