We are a multidisciplinary research group of the Université Libre de Bruxelles, which includes biologists, microbiologists, ecological modelers and bioengineers. Our activities focus on the study and modeling of the structure and functioning of aquatic systems (rivers, lakes, estuaries and coastal waters) and their response to natural and anthropogenic changes. Our methodology involves and combines field observations, process level studies under field and laboratory-controlled conditions and ecological and biogeochemical modeling.
