Extended BIOGRAPHY
Dr. Ioannis Tomkos (B.Sc., M.Sc., Ph.D.), is with the Athens Information Technology Center (AIT), since Sep 2002. He was elected “Adjunct Professor” at the College of Optical Sciences of University of Arizona (2013) and “Adjunct Faculty Research Fellow” at the Department of Electrical and Computer Engineering at University of Cyprus (2014). In the past, he was an Adjunct Faculty member at the Information Networking Institute of Carnegie-Mellon University, USA (2002 - 2010), a senior scientist (1999 - 2002) at Corning Inc. USA and a research fellow (1995 - 1999) at University of Athens, Greece.

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 (most notably from his position as Associate Dean the period 2004-2009). In 2002 he founded the “Optical Networking” laboratory at AIT. At AIT he also founded (in 2002) and serves as the Head of the “High Speed Networks and Optical Communication (NOC)” Research Group, which performs advanced research related with its areas of interest. The NOC group participates in a record number of EU funded research projects related with optical communications and networking (Horizon 2020 ICT-2 STREP DIMENSION, Horizon 2020 ICT-1 STREP ACINO, FP7 ICT-11 STREP INSPACE, FP7 ICT-8 STREP ASTRON, FP7 ICT-8 STREP FOX-C, FP7 ICT-8 STREP COCONUT, FP7 ICT-7 STREP NAVOLCHI, FP7 ICT-5 STREP CHRON, FP7 ICT-4 STREP ACCORDANCE, FP7 ICT-4 STREP SOFI, 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, COST-IC0804) and in national Greek projects (GSRT PANDA) as well as in industry funded research/consulting projects (i.e. from Cisco USA, HOL, Intracom, etc.) in all of which Dr. Tomkos is representing AIT as Principal Investigator. In the majority of these projects Dr. Tomkos also has a consortium-wide leading role as he is/was: the Project Leader of the EU ICT STREP project INSPACE, the Project Leader of the EU ICT STREP project ASTRON, the Project Leader of the EU ICT STREP project FOX-C, the Project Leader of the EU ICT STREP project ACCORDANCE, Project Leader of the EU ICT STREP project DICONET, Technical Manager of the EU ICT STREP project SOFI, Technical Manager of the EU IST STREP project TRIUMPH, Chairman of the EU COST 291 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 (most notably in 2012 I received a research grant from Cisco; one of the very few that are awarded outside USA). Dr. Tomkos in 2011 was the chairman of the Working Group on “Core Network design and transmission systems” within the GreenTouch Initiative/Consortium, an industry-driven initiative focusing on improving the energy efficiency of telecom networks, and a member of the industry-driven Fiber to the Home Council Europe which aims to promote the deployment of FTTH in Europe. He was also the Chairman of the working group “Next generation networks” of the “Digital Greece 2020” Forum (2010 – 2011). The level of funding raised by AIT due to the research activities of the NOC group exceeds the amount of 8 Million Euros. His current research interests cover technical aspects of telecommunication systems and networks, provisioning of services in next generation cloud networks, data-center networking to support cloud services, 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 policy makers and share-holders/executives of 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). He is currently a Business Mentor at Metavallon assisting start-up companies in their business planning.

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 December 1999, 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 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 (2007-2008). Together with his colleagues and students he has authored over 550 archival publications (an updated list of the published items may be found using the “Google Scholar” or “Publish or Perish” tool; over 340 IEEE sponsored items may be found through IEEE Xplore); of which over 150 peer-reviewed articles published in international scientific journals/magazines/books (about 130 archival items through the ISI Web of Science; over 100 in IEEE sponsored Journals) and about 400 presentations at conferences/workshops (over 240 IEEE sponsored and archival through IEEE Xplore). At IEEE Xplore, Scopus and ISI Web of Science databases, he appears in the top-10 list of authors of all times from all over the world under the very general key-word search “optical networks”. He has co-edited a Springer book entitled “Networks for Grid Applications”, 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 Encyclopaedia 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 over 4800 citations and his h-index=34 (as of Aug’14) according to “Google Scholar” (currently adding new citations with a rate of over 800 per year). He holds 2 patents and has several patent applications. He is a member of the “Photonics21” Technology Platform that prepared the first EU Strategic Research Agenda in Photonics. He is a member of the Fiber to the Home Council Europe. 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". In 2014 he was awarded with the 2014 IEEE/OSA Journal of Lightwave Technology Best Paper Award.
