Research interests

- Structure and reactivity of amorphous and nanocrystalline materials. X-ray and neutron Pair Distribution Function (PDF) analyses.

- Mechanisms of homogeneous and heterogeneous nucleation : role of amorphous precursors, pre-nucleation clusters and aggregation-based nucleation and growth. Impact of nano-confinement on the thermodynamics and kinetics of mineral nucleation in pore spaces. In situ SAXS and GISAXS experiments.

- Hydrophilicity / hydrohobicity of mineral surfaces. Water structure at mineral-water interfaces. Inelastic neutron scattering.

- Interfacial geochemistry : in-situ studies of dissolution processes using X-ray reflectivity. Environmental mineralogy : EXAFS and differential PDF studies of ion adsorption at the mineral-water interface.

- Molecular modeling applied to the study of interfacial geochemistry. DFT-based (DMol3, CASTEP..) and classical force-field simulations (LAMMPS).
