RESEARCH INTERESTS

Modelling of the response of marine ecosystems to climate and anthropogenic changes throughout the understanding of the interactions between planktonic organisms and marine biogeochemical cycles (C, N, P, Si), with particular emphasis on eutrophication and air-sea exchange of CO2 and the coupling of rivers and coastal models.
