Emmanouil Kriezis was born in Thessaloniki in 1968. He received his diploma in Electrical Engineering and his Doctorate degree from the School of Electrical & Computer Engineering, Aristotle University of Thessaloniki, in 1991 and 1996, respectively. His doctoral thesis focused on the development of full vector beam propagation methods for light wave propagation in integrated optical devices. In 1998 he jointed the University of Oxford, Department of Engineering Science, initially as an EPSRC post-doctoral researcher. In 2000 he moved into a grant directly funded by the Hewlett Packard Laboratories at Bristol. In 2001 he was awarded the prestigious Royal Society University Research Fellowship to study light propagation in complex anisotropic media.

Since 2014 he has been Professor in Optical & Microwave Communications at the School of Electrical & Computer Engineering, Aristotle University of Thessaloniki. He is teaching the undergraduate courses Optical Communications (8th semester), Microwaves (9th semester) and Photonics Technology (9th semester), together with a postgraduate course on advanced photonics. His research interests include nanophotonics with emphasis on plasmonics, integrated photonic devices on silicon, nonlinear phenomena, optical micro-structured fibers, advanced computational techniques for the analysis and design of photonic devices and circuits, liquid crystal photonics and diffractive optical elements.

He is an IEEE Senior Member and also a member of the Technical Chamber of Greece.

Alexandros Pitilakis was born in Thessaloniki in 1982. He received his diploma in Electrical Engineering from the School of Electrical & Computer Engineering, Aristotle University of Thessaloniki, in 2005, and his Masters degree in Electrical Engineering from the ENST (Telecom) Paris in 2007. Part of his MSc formation was a 6-month internship at the Alcatel-Lucent Optical Transmission Systems group in Marcoussis, France, where he worked on dispersion management of heterogeneous optical fiber networks. He received his PhD degree from AUTH in 2013, under the supervision of Prof. Kriezis, his thesis topic being the "analysis and design of integrated photonic devices based on the hybrid conductor - dielectric - silicon technology", and has continued to collaborate with the Photonics Group.

Alexandros teaches undergraduate antennas & propagation, photonics and optics courses in the UOWM. He has also collaborated with the the Centre for Research & Technology Hellas (CERTH) and the Foundation for Research and Technology Hellas (FORTH), in terms of European research projects.

His research interests include computational electromagnetics, nonlinear and electro-optics in graphene, integrated silicon photonics, plasmonics, waveguides & propagation (optical, THz, RF), metamaterials, antennas and optical fiber communications systems.

He is a senior IEEE member, a member of Optica (formerly OSA) and a member of the Technical Chamber of Greece (TEE).
