After an EPF engineering degree and a DEA in theoretical physics in 1993, I completed a PhD thesis in theoretical nuclear structure at CEA. I hold a permanent position at CEA since 1997, and an HDR since 2011. My work focuses on the spectroscopy of nuclei and their beta or gamma decay using microscopic approaches based on average field approximation. While theoretical and academic studies are an important part of my research work, most of our results/predictions compare to experimental data. When recent data are available, the studies are published in collaboration with experimental physicists (charge radii, magnetic moments, nature of the first collective states, giant and pygmy nuclear resonances…). I have recently extended my activities to nuclear data, mainly strength functions derived from microscopic calculations to improve the predictability of nuclear reaction models. I am also involved in studies on future effective interactions.
