The Biogeochemistry and Modelling of the Earth System (BGéoSys) research group of the Université Libre de Bruxelles has expertise in a range of research fields, from the biogeochemistry of continental and marine systems, the kinetics of ‘water - rock - microorganism’ processes to the modelling of the Earth system. The group focuses mainly on the carbon and nutrient cycles and on their role in shaping the present and past climates on Earth.

More specifically, the research concentrates on the following topics:
- Modelling of the Earth system;
- Hydrological and biogeochemical cycles (C, N, P, Si, S, Fe): weathering, land - ocean - atmosphere exchange, marine (bio)geochemistry, benthic hypoxia, early diagenesis and sedimentology;
- Geochemistry of contaminants (heavy metals, N, P) in aquatic and soil systems;
- Geomicrobial processes at the ‘water - rock - microorganism’-interface (i.e. fungi and bacteria);
- Carbon and nitrogen cycles, green-house gases (CO2, CH4, N2O), ocean acidification, marine calcification and climate, marine biological nitrogen fixation;
- Biogeochemical and geomicrobial dynamics in the sedimentary systems;
- Palaeoenvironments and palaeoclimate: archiving and tracing of processes in geological records;
- Water and fossil fuels resources.
