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 institution of higher education characterized by 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 University of La Mediterranee (France). He is reviewer for over 80 leading international journals, member of the editorial board of two international peer–reviewed journals, and has published more than 150 research papers. Since 2010, he is 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 many international conferences and is member of the International Steering Committee of ESAT (European Symposium on Applied Thermodynamics), JETC (Joint European Thermodynamics Conference) and JEEP (Joint European days on Equilibrium between Phases). His research interests include the development of predictive thermodynamic models based on the group contribution concept, the measurement and correlation of liquid-vapour equilibrium under high pressure and the process and product design.
