Fields of interest: crystallography, X-ray powder diffraction and reactivity of solids
- Elaboration of porous hybrid materials (PCPs, MOFs) based on metal polyhedra and metal-clusters using commercial or original ligands (luminescent, chiral ones) for environmental applications (molecules storage/selection, catalysis, sensors).
- Microstructural analysis of the materials: preparation of nanocrystalline materials (powders); understanding of the formation and nature of the defects within nanocrystalline solids (reticular distorsions, crystallite size, stacking faults); microstructural analysis of oxides and sulfides used as catalysts, semiconductors, electrode materials ....
- Member of the Scientific Committee of EPDIC (European Powder Diffraction Conference),
- Member of the Scientific Committee of the Conference Rayons X et Matière.
- synthesis of coordination polymers and MOFs through solvothermal synthesis routes and mechanochemistry.
- Structural analysis of the materials from single-crystals and powders: ab initio structure determination using methods operating in reciprocal space and in real space from single-crystal and powder XRD data; refinements of the structural models (Rietveld method).
- Microstructural analysis of the materials: preparation of nanocrystalline materials (powders); understanding of the formation and nature of the defects within nanocrystalline solids (reticular distorsions, crystallite size, stacking faults); microstructural analysis by line-profile analysis of X-ray powder diffraction patterns (integral-breadth method, Fourier analysis with writting of a software).
- Multi-scale analysis of materials: combination of diffraction (XRD) and spectroscopy (FPG NMR) techniques for the study of the diffusion of guest molecules in porous host structures
- Teachings at Université de Rennes 1: mainly courses on crystallography, X-ray powder diffraction, inorganic and general chemistry, materials science, porous materials, students projects with industrial partners. Levels: Graduate School of Engineering (Ecole Supérieure d’Ingénieurs de Rennes: http://esir.univ-rennes1.fr), licence and master levels; courses in Master in materials science.
- Invited Professor in Santiago (Chili) in 2013 & 2015: courses on X-ray powder diffraction.
- Member of the Board of Directors (Conseil de Direction) and member of the study council (Conseil d'Ecole) at Ecole Supérieure d’Ingénieurs de Rennes.
- Responsible of the Materials Science diploma (Spécialité Matériaux), a three-year course, at Ecole Supérieure d’Ingénieurs de Rennes.
