Professor Christos N. Markides is Professor of Clean Energy Technologies and Head of the Clean Energy Process (CEP) Laboratory in the Department of Chemical Engineering at Imperial College London. He also leads the Department’s Energy Research Theme, and the cross-faculty Energy Infrastructure Network. His current research interests focus primarily on the application of fundamental principles of thermodynamics, fluid mechanics, and heat and mass transfer to innovative renewable energy technologies, high-performance components, devices and systems for energy (heat, power, cooling) recovery, conversion, integration and storage, with an emphasis on the efficient and cost-effective utilisation of low-temperature (solar or waste) heat. He has written more than 600 scientific articles in these areas, including sole-author and review articles, that have been published in relevant journals or presented at international conferences.
