J. Ramousse is an engineer from the Ecole Nationale Supérieure d’Electricité et de Mécanique – ENSEM, and defended his PhD on Proton Exchange Membrane Fuel Cells modelling at Laboratoire of Energétique Mécanique Théorique et Appliquée – LEMTA – from the Université de Lorraine, Nancy - France in 2005. After a two-year postdoctoral position at Hydrogen Research Institute – IRH - at Trois-Rivières - Canada, he was hired as an associate professor in Université Savoie Mont Blanc in the laboratory LOCIE, Chambéry - France in 2008. He has been equated to a full professor (Habilitation à Diriger des Recherches) in 2018. His areas of expertise are thermodynamic analysis, simulation and the optimization of energy systems. His research activities deal with energy efficiency both at system and district scales, based on thermodynamic approach including exergy and economic assessments. Among the studied systems, his main works deal with fuel cells, thermoelectric devices, absorption systems, interconnected district energy networks and urban metabolism, with openings towards multi-disciplinary approaches. He is involved in various research projects, both with industrial partners or undertaken with public funding. He is the author of more than 25 peer-review papers and 40 international conferences and actively participates to IEA DHC program.
