Research activities

Keywords : Crystallography, X-rays, Solid-state, Phase transition, High-pressure, Low-temperature, Molecular crystals, Spin-crossover, Multi-functional materials.

Main efforts are focused on the investigation of phase transitions and the relationships between structural and physical properties in solids with a preference, but not exclusively, for molecular materials. These studies fall within the field of expertise of crystallography and address the different scales of matter (sub-nanoscopic to macroscopic, including microstructures), distinct environments (temperature, pressure, light) and various types of samples (crystals, nanoparticles, powders, films, raw material). Beyond the fundamental questioning aiming at understanding the physical phenomena studied (mainly connected to magnetism, conductivity, optical features), the ambition is very clearly to guide towards obtaining materials having adequate properties for future applications. In course of the years, a special attention was paid to molecular superconductors, molecular magnets, spin-crossover phenomenon and organic-inorganic hybrid materials.

Teaching activities

Professional credo in a flash : Unquestionably, teaching is deeply the heart of my professional commitment. Increasing fundamental knowledge, as much as possible, through cutting-edge research work fits into this framework. The crystallography allows to combine pioneering experimental investigations, analyses of innovative solutions for the design of materials of the future, advanced transdisciplinary teaching also flirting with the popularization of science and beauty of matter. A passion « all in one ».

Indiscutablement, enseigner est profondément au cœur de mon engagement professionnel. Accroître la connaissance fondamentale, autant que faire se peut, par un travail de recherche de pointe s’inscrit dans ce cadre. La cristallographie permet d’allier investigations expérimentales pionnières, analyses de solutions innovantes pour le design de matériaux du futur, enseignement transdisciplinaire avancé flirtant aussi avec vulgarisation scientifique et beauté de la matière. Une passion « Tout en un ».

Around 200 hours / year teaching at University (all levels) in Physics (Condensed Matter / Electromagnetism / Optics / X-rays / Crystallography)

Activities around popular science (conferences, exposition, articles, workshop)
