Curriculum Vitae


Introduction

My research is focused on nanoscience and on the use of new in situ and real time experimental methods based on Low Energy Electron Microscopy and X-ray Scattering (synchrotron radiation). The goal is to study out-of-equilibrium surface phenomena at the nanometer scale. For the past 15 years, I have developed the use of in situ Grazing Incidence Small Angle X-ray Scattering to study in Fourier space in particular the self-organization of nanosize clusters and the growth of dendritic facetted structures formed during the dewetting of an unstable thin solid film. For the past 7 years, in situ Low Energy Electron Microscopy have been dedicated to surface modification studies on structural and morphological properties induced by a thermal, a chemical or an electrical stress. This research activity is mainly focused on out-of-equilibrium phenomena, e.g. the solid-solid-vapor triple line dynamics, and on the development of a setup based on holography with low energy electrons.

Research carreer

1-Mobility
After engineering studies in Physics (Grenoble Institute of Technology) then "Agrégation de Physique", I have done a PhD at CEA-Grenoble (2001-2004) under the supervision of Gilles Renaud and Jean-René Régnard. Title: « Small Angle X-ray Scattering applied to the in situ growth of nanostructures: towards self-organized growth».

2004-2005 Post-doctoral position at the Max-Planck for Solid State physics (Stuttgart; resp. K. Kern) on growth and characterization of two dimensionnal organometallic layers (Scanning Tunneling Microscopy).

From 2005 to 2016 I was Associate Professor (Habilitation, 2013) at Aix-Marseille University. My research was done at the Interdisciplinary Center for Nanoscience of Marseille (CINaM, dir. Frédéric Fagès).

Since 2016 I am full professor. My research is dedicated to studies on "structure and dynamics of surfaces".
