Offer Description
In the framework of the EU-funded ERC project "Precipitation Triggered Rock Dynamics: the missing mesoscopic link" (PRD-Trigger), you will be in charge of studying salt weathering in building stones or analogous model porous media, by means of laboratory testing and X-ray micro-computed tomography scanning. Dynamic experiments will be carried out in the laboratory and inside X-ray scanners, making use of climatic chambers that have been acquired in the framework of the PRD-Trigger project. In addition, mechanical tests will be carried out on salt-loaded samples, in-situ in the X-ray scanners, using a Deben compression-tensile stage. The research goal is to contribute to a better understanding of the thermo-hydro-chemo-mechanical coupling during salt weathering processes, in order to propose improved or novel conservation strategies for building stones.
Your principal tasks will consist of:
Evaluating salt weathering test protocols
Performing dynamic experiments in the laboratory and in X-ray tomography scanners
Exploiting X-ray images to extract quantitative data and interpretation of these data in the context of salt weathering
Writing experimental reports, storage and documenting of the acquired experimental data following the data management plan of PRD-Trigger
Working in collaboration with the PRD-Trigger project engineer and other engineers in the laboratory, as well as with interns
Participating in scientific and vulgarizing communication actions
Writing scientific articles
You will work within the framework of the ERC project PRD-Trigger, led by Dr. Hannelore Derluyn (CNRS Associate Scientist). The research activities are hosted at the Laboratory of Complex Fluids and their Reservoirs (LFCR UMR 5150, lfc.univ-pau.fr) and the Pau Centre for X-ray Imaging (DMEX UAR 3360, imagingcenter.univ-pau.fr) at the University of Pau & Pays Adour (UPPA) in France, on its campus in Pau.
UPPA is a laureate of the French Science Innovation Excellence Initiative I-SITE (one of only 8 universities in France, e2s-uppa.eu). The LFCR consists of about 140 members (80 non-permanent, 45 permanent staff and 15 support staff) and its research focuses on the behavior of fluids and reservoirs, and the coupling between them, from nano to reservoir scale. The multi-disciplinary character of the laboratory is reflected by the research groups of which it consists, working on: (1) geomechanics and porous media, (2) characterization of geological reservoirs, (3) interfaces and dispersed systems and (4) thermophysical properties. The PRD-Trigger project inscribes into the transversal research axes of the laboratory spanning the different research groups, focusing on multi-scale numerical approaches and experimental imaging techniques. DMEX is a service unit, ISO 9001 certified since 2017, whose mission is to provide services related to X-ray imaging and material characterization, both to academic and industrial (TotalEnergies, TEREGA, STORENGY, SAFT,…) partners.
