Nathalie Niquil is a modeler of ecological and socio-ecological networks. She works in Caen in the BOREA unit (Biology of Aquatic Organisms and Ecosystems, MNHN, CNRS, IRD, UA, University of Caen Normandy, Sorbonne University), where she is in charge of the EcoFunc team (Functional Ecology of coastal food webs and socio-ecological systems). Her work focuses, for example, on the modelling and characterisation of the functioning of microbial food webs or on the development of indicators of ecosystem health for the Marine Strategy Framework Directive. For 5 years, she led the expert group on food webs within the framework of the OSPAR Convention on Regional Seas. She is also interested in cumulative impacts on marine ecosystems (climate change, marine energy, fisheries and pollution) and in the development of numerical methods to model their effects on ecosystem functioning and quantify the associated uncertainty.
