**Research Interest** I am interested in ultra-thin magnetic thin films and more particularly on femtomagnetism. To probe the magnetization in such thin materials I am mainly using soft x-rays and XUV. The interactions between XUV/x-rays with matter allow to have a spatial resolution of the order of the nanometer, to be chemically selective and to be magnetic sensitive. Depending on the used geometry: in transmission, reflectivity or scattering one can be sensitive in depth, or in the sample plane. My favourite technique is to use x-ray Resonant Magnetic Reflectivity (XRMR) to probe the inhomogeneity of the magnetization in depth. To be time resolved I am using XUV/X-rays pulses of hundreds of femtoseconds provided by femtoslicing or Free Electron Laser (FEL) sources at SOLEIL, BESSY, LCLS, FLASH, FERMI, European XFEL, as well as High Harmonic Generation sources at the Laboratoire d'Optique Appliqué. --- **Fundings** 2018-2021: CNRS Momentum <> 2014: Post-doctoral grant of « Direction Général des Armements (DGA) » --- **Professional Experience** **Chargée de Recherche, Sorbonne Université, Paris, France** Study of ultrafast magnetization dynamics by time- and spatial-resolved x-ray scattering and spectroscopy experiment. - Laboratoire Chimie Physique - Matière et Rayonnement - Responsible of the time-resolved x-ray resonant magnetic reflectivity activity and femtoslicing experiments - Performing time resolved experiment measurements: all optical, XFEL Oct 2017 – present **Teaching assistant and Postdoctoral Fellow, Sorbonne Université, Paris, France** Study of the ultrafast magnetization dynamics thanks to time- and spatial-resolved X-ray scattering and spectroscopy experiment - Laboratoire Chimie Physique - Matière et Rayonnement, Jan Lüning - Teaching chemistry and physics at undergraduate level - Growing thin magnetic films by sputtering - Responsible of the time-resolved x-ray resonant magnetic reflectivity activity - Performing time resolved experiment measurements Sept 2015 – Sep 2017 **Research Associate at SLAC, Stanford, USA** X-ray spectroscopy with temporal (fs) and spatial (nm) resolution to study all optical switching in ferromagnetic materials - Stanford Institute for Materials &amp; Energy Sciences, H.
