Christine Rousselle is a Professor, leader of Ammonia projects at Université d’Orléans
Christine Rousselle’s research focuses on low- and zero-carbon combustion technologies, with particular emphasis on ammonia-based fuels. Her expertise spans fundamental combustion science to engine and industrial applications, including liquid fuel injection, advanced combustion modes and optical diagnostics. A key aspect of her work is the characterisation of liquid ammonia sprays—covering atomization, evaporation, and mixing processes—which is essential for understanding and controlling combustion and emissions. She leads several research projects on ammonia as a fuel for engines and, more recently, for the decarbonization of industrial furnaces.
What is your motivation to join DT-HATS?
DT-HATS brings together academia and industry to tackle key challenges in liquid ammonia and hydrogen injection through a unique combination of experiments and modelling. I joined the project to contribute to this integrated approach and to help train the next generation of researchers in carbon-free combustion technologies.
