After completing an engineering degree in optics and numerical modeling, I pursued a PhD in plasma physics at CEA Paris-Saclay, within the Laboratory of Interactions, Dynamics and Lasers, under the supervision of Fabien QUÉRÉ. My research focused particularly on understanding the mechanisms of laser-plasma coupling in the relativistic regime, as well as on the spatio-temporal characterization and control of intense attosecond XUV pulses generated during these extreme interactions. I then joined CEA DAM Île-de-France, where I have primarily worked on the design of plasma diagnostics for the LMJ-PETAL facility. In parallel, I contributed significantly to the development of innovative X-ray phase contrast and coherent diffraction radiography concepts, notably through the implementation of reconstruction algorithms, conducting experiments at several major facilities (LULI2000, ESRF and SACLA) and supervising students and collaborations.
