George Apostolopoulos received his BSc (1991) and PhD (1997) degrees from the Physics Department of the National University of Athens, Greece. He has worked at the Paul-Drude Institut, Berlin (1997-2000) and the Institute of Materials Science of NCSR "Demokritos" (2000-2003). During this period his work has been mainly devoted to the growth and characterization of semiconductor materials and devices. In 2004 he joined the Institute of Nuclear Technology and Radiation Protection of NCSR "Demokritos" as a research associate, working on the development and application of neutron and X-ray scattering techniques in the characterization of materials. Since 2008 he is a researcher of the Institute. His current research focuses on the properties of materials for future fusion energy systems and particularly on the effects of radiation damage and recovery.
