About CEREGE:
The CEREGE is an international multidisciplinary research and teaching center, that covers almost all the Environmental Geosciences, from Martian mineralogy to water treatment, tectonics, paleoclimatology, geochemistry, physical chemistry and process analysis. As a center of excellence in terms of human skills and instrumental capabilities, CEREGE's research is based on laboratories and analytical platforms, the inter-team collaborations and an extensive network of national and international collaborations. The thematic teams are supported by state-of-the-art laboratories, multiple areas of expertise and complementary, combining field observation techniques with analytical experimentation and numerical modelling.
Ideally located in the heart of the Technopôle de l'Arbois in Aix-en-Provence, it benefits from optimal conditions for the development of networks and partnerships.
Description of the position:
Trace metals inputs to agricultural soils via fertilizers are of concern due to their potential risk to the environment and human health. The overarching goal of the DUNE project (Cadmium and Trace Elements Bio-Availability and Transfer In Soil-Plant- System) is to enhance our understanding of Cd bioavailability to crops and its bio-accumulation within the soil-plant system. To that end, it is primordial to tackle the Cd biogeochemical cycle and dynamic, and to put effort into characterizing Cd sources (pedogenetic and anthropogenetic) in the environment as well as understanding what controls its bioavailability down to a molecular level. The DUNE project will bring further knowledge on the uptake mechanisms and fate (translocation, accumulation) of Cd and trace elements in crops and their rhizosphere.
The postdoctoral project will focus on characterizing the source of Cd contaminant (soil, fertilizers, water) into top-soils and understanding what controls the bioavailability of Cd and trace elements. The objective is to investigate the fate of Cd in the biota using an innovative and unique approach combining cutting-edge Cd stable isotope analysis to X-ray spectroscopy measurements of Cd speciation to understand the main processes that control Cd bioavailability.
Cadmium stable isotope analysis in soils, fertilizers and plants will be performed on CEREGE’s multi-collector mass spectrometer MC-ICPMS Thermofischer Neptune+.
The speciation and location of the elements of interest will be determined by state-of-the-art methodology based on a multiple scale characterization combining techniques at CEREGE and synchrotron radiation facilities including X-ray Absorption Spectroscopies (XAS, XRF) and imaging techniques (Micro-XAS, micro-XRF,…).
The recruited person will work in France (CEREGE, Aix en Provence) and Morocco (UM6P AITTC-experimental farm).
Mohammed VI Polytechnic University is an institution oriented towards applied research and innovation with a focus on Africa.
