Michalis Vardavoulias

PyroGenesis Managing Director and Chief Technology Officer

Michalis Vardavoulias has more than 30 years of experience in Materials Science and Surface Modification Technologies. He obtained both, his Engineering Diploma in Metallurgy and his Ph.D degree (Bodosakis Foundation fellowship) in Materials Science, from the National Technical University of Athens, Department of Mining and Metallurgical Engineering, Laboratory of Materials Technology.

He worked for 5 years as a Senior Research Engineer in Tribology and Surface Modification Technologies at the Centre of Materials of the “Ecole des Mines” of Paris.

He organised and managed the Thermal Spray and Tribology Department at EBETAM/CERECO (Ceramics and Refractories RTD Centre, Greece).

Between 1998 and 2000 he was the Project Manager of the Hellenic Innovation Relay Centre.

In 2000 he co-founded PyroGenesis SA, an innovative SME dealing with Advanced Materials and Coating Technologies, and he is since that date Managing Director and Chief Technology Officer in the company.

He has participated in more than 35 funded EU and National Research Projects and was the coordinator in some of them. He has published more than 130 original research and technical papers in international scientific journals and conference proceedings. 

In 2007 and 2008, Dr Vardavoulias was a visiting Professor of Materials Science and Technology in the Department of Production Engineers, Polytechnic School, Democritus University of Thrace.

Since 2012, he is the Greek Delegate in European Thermal Spray Association

In the last years his main interest is the commercialization of new Thermal Spray applications
