Spyros Messoloras is Research Director Emeritus. He graduated from the Physics Department of the University of Athens and he obtained his PhD from the Physics Department of the University of Reading, in UK. In the period 1975-1984 he served as Senior Research Fellow at the University of Reading, UK and subsequently he was appointed Assistant Professor at the Physics Department of the University of Athens. In 1995 he got the position of Research Director at the National Centre for Scientific Research “Demokritos”. He has carried out research at A.E.R.E. Aldermaston, U.K., U.K.A.E.A. Harwell, U.K., S.E.R.C. Rutherford and Appleton Laboratory, U.K., Institut Laue-Langevin, France, Daresbury Laboratory, U.K., and Hahn-Meitner Institut, Germany He has been member of the Science and Technology Advisory Committee of the European Fusion Programme (1999 - 2007), member of the EUROfusion Scientific Boards in Materials and JET2 and JET3 sub-projects (2014-2019) and national representative in the European Neutron Scattering Association (2000 - 2007). His research interests include among others radiation damage in alloys and semiconductors, fusion energy materials, structural and mechanical properties of alloys, crystalline and amorphous magnetic materials, magnetic thin films and multilayer structures, semiconductor materials & semiconducting multilayer structures, molten salts and liquids, data reduction, analysis software development and numerical modelling.
