During my PhD, I studied the fragmentation of simple molecules under the impact of ions from the Grand Accélérateur National d’Ions Lourds (GANIL) in Caen. Then in 2003, I joined the CEA/DIF as a postdoctoral researcher, where I focused on the interactions between the atomic nucleus and its peripheral electrons. This experimental work, at the interface between nuclear physics and atomic physics, led me to be recruited in 2004 as a lecturer-researcher at the University of Bordeaux, within the Centre d’Etudes Nucléaires de Bordeaux Gradignan (CENBG) laboratory. There, I conducted research on the properties of atomic nuclei immersed in astrophysical-type plasmas generated by high-power laser shots. In order to produce radioisotopes of interest in this extreme and very short-lived environment, I focused on laser-plasma acceleration to generate ultra-intense sources of gamma photons, ions, and neutrons. These sources are also very promising for research into innovative medical radioisotopes for vectorized internal radiotherapy. In parallel with these research activities, I have carried out my teaching duties in the GEII department of the Bordeaux University Institute of Technology, where I have been Director of Studies for three years. Attracted by innovative instrumentation and driven by the desire to invest myself in an ambitious and visionary scientific project, in 2025 I seized the opportunity to join the teams working on the Laser Megajoule.
