I. A propos
She received her Ph.D. degree at the Claude Bernard University in Lyon. The main objective of her Ph.D. dissertation was to demonstrate the use of linear and non linear optical techniques to characterize molecule and metallic nanoparticle monolayers at liquid interfaces. She got her first post-doctoral position at the Geneva University. During one year, she developed an experimental methodology, based on ultrafast second harmonic generation, to probe photoinduced molecular dynamic at liquid interfaces. The second post-doctoral position at the CEA Marcoule was devoted to set up the second harmonic generation experiments for industrial applications in nuclear fuel recycling processes.She joined, as a lecturer, the University of Montpellier 2 in September 2012.
Her research work is actually focused on structuration, confinement, solvation effects and molecular arrangement for “in situ” systems, particularly onto porous nanoparticules and nano-structured interfaces like clays, nanotubes, zeolites, aggregates or liposomes in liquids.

II. Activités de recherche
Probing interfaces and molecular structures with second harmonic processes
The non-linear optical techniques developed in D3 has the noteworthy advantage to be highly sensitive to interfaces and symmetry breaking systems at the molecular level. This technique allows to quantify, the organization and the interactions between molecules under “in situ” conditions in liquids. Many parameters may be accessible like the adsorption/ encapsulation quantification, the electric double-layer structure, the chemical interactions, the ionic complexation, specifically close to interfaces or inside molecular arrangements. Moreover, it gives access in real time to the interfacial dynamic. Confinement and solvation effects are actually explored in hydrophilic/hydrophobic porous systems.
