I joined CEA in 2023 after a PhD at Ecole polytechnique on the ab initio simulation of strongly correlated materials. I am now interested in Warm Dense Matter (WDM), a regime of matter between the solid and plasma states. I study by ab initio approaches various phenomena such as X-ray absorption, optical conductivity and electron-ion thermal relaxation. To this end, I use and develop in the ABINIT code methods based on the Density Functional Theory (DFT) which is able to describe the electronic structure. To simulate the behavior of atomic nuclei, these methods are coupled to Molecular Dynamics (MD).
