Efstratios Kehayas (PhD, MSc, DIC, BEng) is a chartered Electrical & Computer Engineer and has performed R&D on photonics for various SMEs and research centers within the Greek sector. Dr Kehayas has more than 10 years of experience on photonics R&D with specialization in the design and development of optical fibre systems and integrated photonic components. He held various research and management positions in national and European R&D projects where he worked on the development of optical sources, optical fibre amplifiers, photonic processing systems and optical transmission sub-systems with successful technology transfer and commercialization of several of his research activities. In the period 2005-2008 he raised more than 1.5 Meuros in R&D funding, enabling the design and development of new generation of transmission and processing systems for high-speed optical core and access networks. He has 2 granted patents, has authored and co-authored more than 70 contributed and invited scientific publications in IEEE and OSA journals and conferences, and has organized various workshops in conferences on optical fiber communications. Since 2011 he is a member of the Young Advisory Group (YAG) of European Commission Vice-President Neelie Kroes. He concentrates on providing feedback on the European Digital Agenda 2020, focusing on creating innovation- and entrepreneurship-friendly R&D eco-systems in Europe. Dr Kehayas obtained the B.Eng. degree from Southampton University, Electronics & Computer Science Department, the MSc degree in Optics & Photonics from Imperial College London and the PhD degree from the National Technical University of Athens, School of Electrical & Computer Engineering.
