Dr Spilios Dellis is a post-doctoral researcher at the Fusion Technology Group (FTG) of the Institute of Nuclear and Radiological Sciences and Technology, Energy and Safety of NCSR "Demokritos", since February 2018 and he works in the framework of the European Consortium for the Development of Fusion Energy (EUROfusion).

His research topics refer to the study of radiation damage of metals and alloys for fusion energy applications employing nano/micro indentation and impulse excitation technique.

He received his PhD degree in 2018 from the Physics Department of the Aristotle University of Thessaloniki. His PhD was on the enhancement and tailoring of photoluminescence of semiconductors using metallic nanostructures. He received his MSc in Condensed Matter Physics in 2013 from the Physics Department of the University of Patras. He received his BSc in Physics in 2011 from the Physics Department of the University of Patras.

He has worked in the research projects: “Formation and Characterization of Plasmonic Nanoparticles” (SMARTONICS-FP7, 2017), “Laser Annealing for Improved Flexible Electronics” (EPSRC Centre for Innovative Manufacturing in Large-Area Electronics, 2016), “NANOMEGAS/NANOMEsh Gaseous Structure” (NANOMEGAS, Carathéodory funding scheme 2012-2013).

He has published 7 articles in peer-reviewed scientific journals, and he has participated in 15 contributions in international conferences.
