Professor Spiros Alexopoulos works in the Department of Energy Technology at the FH Aachen University of Applied Sciences. He received his intermediate diploma in physics from the Westfälischen Wilhelms-University Münster (1995) and his diploma in physics from the Rheinischen FriedrichWilhelms-University Bonn (1999). He received his PhD in mechanical engineering from the University of Siegen, Germany (2003), and he was then a doctoral researcher at the Institute of Thermal Thermodynamics, Solar Research, at the German Aerospace Center, Köln-Porz, Germany. He was employed as a research associate by Solar-Institut Jülich from 2005 to 2010 and became head of the Regenerative Systems Department in 2011. In 2014, he became a professor at the FH Aachen University of Applied Sciences and he is now head of the Laboratory for Thermodynamics. Since 2015, he has been a member of the board of directors of the Solar-Institut Jülich at the FH Aachen University of Applied Sciences. His research interests include solar thermal systems, (hybrid) solar tower power plants, water desalination using solar energy, and energy system solutions for the Mediterranean region.Professor Soteris A. Kalogirou works in the Department of Mechanical Engineering and Materials Sciences and Engineering at the Cyprus University of Technology, Limassol, Cyprus. He is currently the dean of the School of Engineering and Technology. In addition to his Ph.D., he holds the title of D. Sc. He is a fellow of the European Academy of Sciences and founding member of the Cyprus Academy of Sciences, Letters and Arts. For more than 35 years, he has been actively involved with research in the area of solar energy and particularly in flat plate and concentrating collectors, solar water heating, solar steam-generating systems, desalination, photovoltaics, geothermal energy, and absorption cooling. He has a large number of publications as books, book chapters, international scientific journals, and refereed conference proceedings. He is the editor-in-chief of Renewable Energy, deputy editor-in-chief of Energy, and editorial board member of another 20 journals. Professor Kalogirou is the editor of the book Artificial Intelligence in Energy and Renewable Energy Systems, published by Nova Science Inc.; co-editor of the book Soft Computing in Green and Renewable Energy Systems, published by Springer; editor of the book McEvoy’s Handbook of Photovoltaics, published by Academic Press of Elsevier; and author of the books Solar Energy Engineering: Processes and Systems and Thermal Solar Desalination: Methods and Systems, published by Academic Press of Elsevier. He is a member of the World Renewable Energy Network (WREN), American Society of Heating Refrigeration and Air-conditioning Engineers (ASHRAE), the Institute of Refrigeration (IoR), and the International Solar Energy Society (ISES).
