Research interests

I am interested in the supramolecular assemblies of biological or biomimetic molecules. For instance, my PhD thesis work was devoted to understanding the physico-chemical conditions that rule type I collagen self-assembly in vitro. We could build biomaterials mimicking biomaterials such as skin or bone, whose main component in vivo is collagen. I have also studied the amyloid-like assembly of short peptides.

More recently, in collaboration with researchers from the Institut Galien and from INSERM, I have focused on the interaction between nanoparticles and proteins in order to better understand the pharmacodynamics of nanodrugs.

Overall, my goals are to understand the kinetics and mechanisms of assembly from the atomic level up to the supramolecular level i.e., from the ångström to the millimeter. This wide range of scales requires combining different techniques of structural characterization: (cryo)transmission electron microscopy, radiation scattering (x-ray and neutron) and vibrational spectroscopies. I also occasionally use microfluidics tools.

These tools led me to expand my fields of interest to mineral systems.

For example, I use SAXS and polarized light microscopy to characterize the nanostructure of lead-based paint mediums. This work is done in collaboration with Laurence de Viguerie from the LAMS who reconstitutes paint formulations from old painters's recipes.

Likewise, cryogenic transmission electron microscopy is also a very useful tool to characterize clay minerals like imogolite nanotubes (with Antoine Thill) and to quench intermediate species during mineral precipitation (projects with Corinne Chevallard and David Carrière).

Mes travaux de recherche s'intéressent principalement à l’étude physico-chimique d’auto-assemblages biologiques ou biomimétiques. Par exemple, au cours de mon travail de thèse j’ai étudié différents aspects des auto-assemblages du collagène de type I, une protéine structurale majeure des tissus conjonctifs chez les vertébrés. J'ai aussi étudié les assemblages peptidiques de type amyloïde.

Mes objectifs sont de contrôler les conditions physico-chimiques et de comprendre les mécanismes d’auto-assemblage depuis le niveau atomique jusqu’au niveau supramoléculaire (de l’angström jusqu’au millimètre). Pour ce faire, je combine différentes techniques de caractérisation : microscopies (optique et électronique), diffusion du rayonnement (SAXS, SANS) et spectroscopies vibrationnelles (infrarouge, dichroïsme circulaire, Raman). Je me suis aussi intéressé au développement d’outils microfluidiques pour la cristallisation des protéines.
