Jean-Noel Jaubert is Professor of Chemical Engineering Thermodynamics at ENSIC (Ecole Nationale Superieure des Industries Chimiques). A Grande Ecole like ENSIC is a state-run higher-education institution with a highly selective admission procedure and is thus restricted to the best 10% of high school students. He was born in 1967 in Marseille, France, and received his doctorate in 1993 from Aix-Marseille University (France). He is a reviewer for over 80 leading international journals, a member of the editorial board of five international peer-reviewed journals, and has published more than 200 research articles in renowned international journals. Since 2010, he has been the French delegate at the working party thermodynamics and transport properties of the European Federation of Chemical Engineering and currently runs the research group “Thermodynamics and Energy” of the LRGP (Laboratoire Réactions et Génie des Procédés) and chairs the French working party of thermodynamics. He organized several international conferences and is a member of the International Steering Committee of ESAT, JETC, and JEEP. His research interests include the development and parameterization of equations of state, the measurement and correlation of liquid-vapor equilibrium under high pressure, the development of the entropy-scaling concept to correlate transport properties, and the use of a product design approach to select efficient working fluids for innovative power and refrigeration cycles.
