Activités / CV

Born in 1972. Master in Material Science at INP-Grenoble in 2000. Post-doc in 2001 at ESRF on the id27 high-pressure beamline. Joined CNRS in 2002, first at LEPMI (UMR 5279 Grenoble) and since 2007 at LMGP to develop high-pressure studies on functional oxydes. From 2007 to 2011 scientific collaborator at Id27 high pressure beamline (ESRF) in charge of optic and spectroscopic aspects (development of an on line Raman setup).
Interested in detailed knowledge of atomic-scale structural change (order parameters, strains) in order to understand the process and mechanism of phase transitions in solids. Mainly interested in ABO3 perovskites and multiferroics and the competitions of different instabilities (tilt, polar displacements, Jahn-Teller) under high-pressure.
