Work Context

This work will be performed at the Institut de minéralogie, de physique des matériaux et de cosmochimie (IMPMC-UMR 7590, Sorbonne Université, 75005 Paris). The IMPMC is a joint research unit of the CNRS, the Sorbonne Université, and the Muséum National d'Histoire Naturelle, counting around 200 members. It is a highly pluridisciplinary laboratory, composed of researchers, researchers-teachers, and engineers with different backgrounds (physics, Earth science, biology, chemistry, computer science, etc.). Various experimental and theoretical research topics are studied at the IMPMC, such as elucidation of the structure of materials and macromolecular assemblies, investigation of their dynamic properties, study of interactions between the living world and the mineral world, etc.

Constraints and risks

18 months, with possibility of extension.
