Sylvain Iséni (GREMI Orléans, France)
Academic Biography I am a Senior Tenured Researcher at the French National Center for Scientific Research (CNRS). My academic journey began at the University of Orléans (France), where I earned both a Master of Science degree and an engineering diploma in 2011. In 2012, I embarked on my doctoral studies at the Leibniz Institute for Plasma Science and Technology (INP Greifswald, Germany). I was awarded a PhD in Physics in 2015 from the University of Greifswald, with a dissertation focused on laser diagnostics of atmospheric pressure plasma jets for biomedical applications. Currently, I am affiliated with the Research Group in the Energetics of Ionized Media (GREMI), a joint laboratory of CNRS and the University of Orléans, France. In may 2024, I obtain the Habilitation degree.
Research Interests My research centers on non-equilibrium (non-thermal) plasmas and their applications in environmental and biological contexts. This includes the development of innovative micro-plasma sources and the investigation of fundamental processes in discharges and plasma-liquid interactions. Key areas of study encompass induced electric fields, electron dynamics, radiation transfer, and non-equilibrium chemical kinetics—particularly those governing the generation of highly reactive species. I have extensively studied guided ionization waves produced by dielectric barrier discharges and plasma jet devices (APPJ). Recently, my focus has expanded to micro-discharges, exploring their potential as a competitive approach for green energy processes using plasma technologies, such as silicon-based micro-hollow cavity discharge (MHCD). My work also involves plasma diagnostics, with a strong emphasis on Optical Emission Spectroscopy (OES) to investigate key plasma parameters, including electric field, electron density, neutral gas temperature, and hydrodynamics. Since 2024, I have returned to my initial field of expertise: laser diagnostic techniques for reactive gases and weakly ionized plasmas, particularly to measure absolute densities of reactive species.
