Main research topics
Trace metal biogeochemistry in riverine, estuarine and marine systems
Ultra-clean sampling, storage and analyses techniques.
Determination of trace metals in organisms, plants, sediments, air, water.
Spatial and seasonal variations in the transport of trace metals.
Biogeochemical cycles of trace elements
Marine barium biogeochemistry
Trace, minor and major elements in non-organic biogenic substrates as tracers of environmental changes (shells of bivalves and calcareous sponges)
Carbon and nitrogen cycling in oceanic and coastal systems
· Production, transport and fate of organic matter and associated elements in marine systems. New production and regenerated production. Tracers of export production.
· Carbon and nitrogen flow in tropical coastal mangrove ecosystems (Kenya, India, Sri Lanka) and in temperate estuaries (e.g. Scheldt river).
· Stable C and N isotope tracers (d13C en d15N ) as a tool to understand trophic relationships in deep-sea hydrothermal communities; coastal, estuarine and riverine ecosystems.
· Biogeochemical cycle of carbon in coastal waters, estuaries and rivers
Modeling of biogeochemical processes in the aquatic environment
· Modeling the biological nitrogen transformation processes in oceanic environments
· Modeling the biogeochemical behaviour of pollutants (trace metals, nutrients, microorganics) in rivers, estuaries and coastal seas.
· Modeling of suspended barite formation and distribution in the Southern Ocean and its relation with the export production.
· Modeling of toxic heavy metal distribution in waterways connecting the city of Brussels with the river Scheldt.
