Building bridges between geology and materials sciences

Renelle Dubosq joins MPIE with fellowship of Canadian Research Council

April 19, 2022

The “Natural Sciences and Engineering Research Council of Canada” (NSERC) awarded Dr. Renelle Dubosq with a postdoctoral fellowship. The fellowship finances a research stay abroad and Dubosq decided to join the Max-Planck-Institut für Eisenforschung (MPIE) for the next two years. Her research focusses on interrogating the deformation and elemental mobility processes in geomaterials. One of her current projects involves developing cryogenic approaches for atom probe tomography with the aim to study nanostructures in water ice as a proxy for monomineralic rocks and investigate the impact of impurities on recrystallization processes.

Dubosq is the only geologist at the MPIE and aims at deepening interdisciplinary research in materials sciences: “It is a great opportunity to work amongst, and learn from, experts in the field of materials sciences as well as having access to world-class, state-of-the-art research facilities. MPIE is a great work environment that fosters collaboration and creativity. During my stay, I look forward to further developing my network of collaborators as well as pushing science forward with the aim of bridging the gaps between geosciences and materials sciences.”

Methodologically, she integrates 2D and 3D structural and geochemical mapping techniques that image and quantify morphology and chemical composition of rock-forming minerals at the atomic scale. To conduct research on this scale, she joined the “Atom Probe Tomography” research group in the “Microstructure Physics and Alloy Design” department. Atom Probe Tomography is a high-resolution characterization technique that provides three-dimensional elemental mapping with near-atomic resolution.

NSERC is a Canadian government agency responsible for funding natural sciences and engineering. It is the largest supporter for scientific talents and natural science research in Canada.
