His research activities are focusing in the fields of hydrocarbons processing (natural gas vaporization and production of olefins), hydrogen (iso-octane and bioethanol reforming, steam and H2S electrolysis, electrochemical membrane reactors for hydrogen generation and separation) and fuel cell (direct hydrocarbon and solid carbon high temperature ceramic fuel cells) technologies, CO2 utilization (hydrogenation to methanol and methane, electrolysis toward CO), air pollution control (NOX, VOCs, etc) and biomass to energy conversion technologies (pyrolysis and gasification of solid biomass and biochar). His scientific work has been published in 96 articles in international journals and in >150 conferences’ proceedings with more than 3100 citations (H = 31). He is a regular reviewer in relevant scientific Journals and research funding agencies. In 2010, he obtained the Fulbright research scholarship to cooperate with MIT (Prof. Yang Shao Horn, Dept. of Mechanical Engineering) in the research field of fuel cells. From 2016 till 2023, he was the chairman of the Cluster of Bioeconomy and Environment in Western Macedonia (CluBE) and since 2020 he is the associate editor of the “Hydrogen” journal of MDPI Editions.

Dr. Costas Athanasiou (Male, Chemical Engineer), Deputy Project Coordinator in ECOLEFINS, is an Assistant Professor of DUTH. His research interests lie in the fields of electrochemical membrane reactors, high temperature fuel cells and biomass energy conversion technologies, where, in addition to their design, optimization and operation, he is an expert in the elaboration of energetic and feasibility studies. He is the author of more than 35 referred papers in high impact factor journals (Citations: > 600, h-index: 11). He has participated in relevant national and European research projects, and he is serving as regular reviewer in several scientific journals and funding agencies.

Dr. Konstantinos Christoforidis (Male, Environmental Engineer) is currently an Associate Professor at the Department of Environmental Engineering of Democritus University of Thrace and since 2019 senior scientists at the Institute of Chemistry and Processes for Energy, Environment and Health, CNRS University of Strasbourg, France.
