He also served as a Researcher at the Center for Electric Power and Energy in the Department of Electrical Engineering at the Technical University of Denmark. In February 2017, he joined the Center for Energy Technologies at Aarhus University as an Associate Professor and was promoted to Full Professor in January 2023. Since January 2024, he has been with the University of the Peloponnese, Dept. of Mechanical Engineering. Additionally, George was a co-founder of VerdeCube and has worked as an adjunct faculty member in the Energy Policy and Climate program at Johns Hopkins University, where he taught the course "Wind Energy: Science, Technology and Policy" (425.624.81). He has also undertaken freelance consulting for various institutes, universities, and SMEs. His research interests include Energy Planning, Wind Resource Assessment, Techno-economics of Renewable Energy Systems, Energy Demand, and Plant Factories. He has co-authored more than 150 publications in international journals and over 50 publications for international conferences, books, and book chapters. He holds an Integrated Master's degree in Mechanical Engineering from the Aristotle University of Thessaloniki and a PhD from the National Technical University of Athens, Greece. George serves as an Associate/Deputy Editor in the Journal of Renewable and Sustainable Energy, the Journal of Business Analytics, and in Energy Sources, Part B: Economics, Planning, and Policy. Since May 2024, he serves as the Co-Editor-in-Chief of "Cambridge Prisms: Energy Transitions", a new journal that Cambridge University Press launched.

Having studied and developed more than 1700 MW of Renewable Energy Projects (mainly wind) has gained significant experience in the field. Dealt with site topography identification, correlation of short-term data with long-term data, estimation of energy production, design & energy yield optimization, analysis of wind resource data from meteorological masts and maps, data mining and data analytics, energy & technical analyses, business plans etc. He has been involved in several EU research projects and fundraising activities. His main research activities include (but are not limited to):
