Contrat à temps plein (100%) pour une durée 2 ans
Entrée en fonction : 1 septembre 2023



We seek a postdoctoral researcher for a multidisciplinary project across four groups: (i) The BGeoSys research group (ULB, Belgium) is dedicated to improve our understanding of the carbon and nutrient cycles and their roles in shaping past and present climates; (ii) The Earth & Life Institute (TECLIM, UCLouvain, Belgium) is driven to understand how landscapes evolve and how this impacts the humans living on these landscapes; (iii) The Surface Earth Evolution (SEE) group in the Department of Earth Sciences at ETHZ is committed to investigate the processes that drive global climate change over human to geologic timescales; (iv) The Sustainable Agroecosystems (SAE) group in the Department of Environmental Systems Sciences at ETHZ is dedicated to understand how agricultural and food systems can bring healthy food from fields to tables around the world for generations to come. Combined, our work intersects traditional Earth and environmental science fields to holistically study the drivers and impacts of changing climate and land use. We effectively integrate field-based sample collection and monitoring with lab-based geochemical measurements and numerical models.

Project background

This position is part of the SNSF-funded project “TropSEDs (Tropical Soil Erosion Dynamics): Unraveling the roles of climate and land-use on the erosional transfer of carbon from source to sink through time in the Kasaï Basin”. The project aims to resolve the controls on—and predict future changes in—the movement and fate of tropical soil carbon in the Kasaï Basin, DR Congo. Specifically, we will sample sediments in rivers, floodplains, ancient lake bottoms, and soils along the Kasaï River. We will assess the amount, age, and source of organic carbon and how this relates to geologic factors such as clay sediment type or environmental factors like land use and climate, both today and over the past ~6,000 years. We will use these measurements to refine computer simulations of Earth’s surface processes to explore the life- cycle of carbon as it is transported from soils (“source”) to its final destination in sediment deposits (“sink”).


Description du poste

You will be responsible for the integrated C erosion model aspects, with the specific duties:

  • Compile and evaluate observational data, setup model-data interactions

  • Implement soil/sediment geochemistry in the ORCHIDEE-Clateral land surface model

  • Assess the impact of terrestrial OC “leakage” that includes dissolved and particulate

    fluxes on the regional OC cycle in the humid tropics

  • Elucidate how climate and land-use regulate carbon storage versus oxidation within

    the Kasaï Basin over different time scales

  • Communicate findings, write scientific papers, and participate in international

    conferences and workshops

    The applicant will be trained by our team in state-of-the-art modelling tools and will proceed in close cooperation with experts in the different fields of TropSEDs. This position is integral to the research team, which includes 4 PhD students and 3 postdoctoral researchers across four groups. You will therefore lead these tasks but will be supported by all involved PIs and postdocs. This multidisciplinary team offers the opportunity to learn, develop, and apply scientific skills beyond traditional earth system modelling.This postdoc will be primarily based in the BGeoSys and ELI research groups (ULB & UCLouvain, Belgium). We offer excellent, inclusive working conditions and a competitive salary. Our laboratories are located nearby in Brussels and Louvain-la-Neuve and the working language is English. Start date will ideally be 1 September 2023 (and the latest 1 October 2023). Additional information regarding ULB and UCLouvain can be found at and at
