Active as a full professor from 1986 to 2020, Dr. Renaud Gicquel has taught a wide variety of subjects, such as applied thermodynamics and global energy issues and energy system modeling. His recent research activities were focused on the optimization of complex thermodynamic plants (heat exchanger networks, cogeneration, combined cycles) and on the use of information and communication technologies for scientific instruction. Renaud’s special interest and passion is the combination of thermodynamics and energy-powered system education with modern information technology tools. To this end, he has developed various software packages to facilitate the teaching and learning of applied thermodynamics and the simulation of energy systems: Thermoptim (Thermo-Calc) professional software, 2000, CSTB, www.cstb.fr Interactive Thermodynamic Charts, 2000 Diapason e-learning modules, 2004, www.thermoptim.org Renaud Giquel is now retired. He was previously Professor at the École des Mines de Paris (Mines ParisTech). He was trained as a mining engineering at the École des Mines and got his doctorate in engineering from the Paris VI University. He started his career as a Special Assistant to the Secretary General of the United Nations Conference on New and Renewable Sources of Energy from in 1980 in New York. He then became the Deputy Director in charge of Dwellings at the Energy Division of the Marcoussis Laboratories of the Compagnie Générale d’Electricité until January 1982, and the Head of multilateral issues in the International Affairs Service of the Ministry for Research and Technology in Paris in 1982. From 1983 to 1985, he was Adviser for International Issues of the National Center of Scientific Research (CNRS). In 1986, he founded with the late Michel Grenon Mediterranean Energy Observatory (OME), based in Sophia Antipolis. In 1990, Dr Gicquel created the ARTEMIS group, a research body for thermal energy research, together with the University of Nantes and ISITEM (now Polytech) in Nantes. He acted as a coordinator and while fulfilling the position of Deputy Director at the Ecole des Mines de Nantes (EMN) from three years form 1991 as well. In 1987 he was named head of the Centre of Energy Studies of the École des Mines de Paris in 1987.
