Research Interests

 

Ecological and biogeochemical modelling of the response of marine ecosystems to climate changes and anthropogenic pressures, throughout the understanding of the interactions between planktonic organisms and marine biogeochemical cycles (C, N, P, Si), and the coupling of rivers and coastal models with particular emphasis on eutrophication and climatic gases.
