Born in Athens in 1964, has graduated in 1986 from Physics department of University of Crete in general physics. He got his MSc and PhD in Plasma Science in 1987 and 1990 from Toulouse 3 University (France). He is today Distinguish-class Professor in Toulouse 3 University (France). His primary area of work is in the field of Light Sources Science and Technology. He is especially interested in the physics of electrical discharges used as light sources; system and metrology issues for solid-state lighting systems; normalization and quality issues for light sources; impact of lighting to energy, environment, quality of life, health and security; interaction between light source and associated power supply; illumination and lighting. He is director of “Light & Matter” research group of LAPLACE that enrolls 20 researchers. He has published more than 156 paper in referenced scientific journals (Hisch index 22 according scopus), more than 300 papers in international conferences. He has given more than 90 invited lectures at international and national events. He was advisor for 36 PhD students. He has coordinated more than 10 major European and international programs (global budget of more than 10 million euros). He won in December 2006 the 1st Award of the International Electrotechnical Committee (IEC) Centenary Challenge for his work on normalization for urban lighting systems (in conjunction with IEEE, IET and the Observer). In 2009, he won the Energy Globe Award for France and he got the Fresnel Medal from the French Illuminating Engineering Society. In 2011 has been awarded the title of Professor Honoris Causa of Saint Petersburg State University (Russian Federation) and he was President of the Power Electronics, Electronics, Optoelectronics and System section of the French National Council of Universities for the period 2014-19. He was President of IEEE Industrial Application Society for 2019-20. He is Chairman of the 4E-Solid State Lighting Annex of the International Energy Agency (2020-24).
