Research interests:
My current research focuses on biogeochemical cycles in tropical forestry ecosystems. I will specialise both on soil-tree nutrient cycles in Eucalyptus spp. plantations, as well in mixed-species indigenous plantations (MataDiv project). These experimental sites are based in Brazil, in the state of São Paulo, in partnership with the University of São Paulo (ESALQ).
My previous research focused on biogeochemical cycling in soil-crop systems during my PhD, with a focus on nitrogen cycling in tropical soil-sugarcane systems in Réunion Island. I subsequently focused on denitrification and N2O emissions in the temperate Danish agricultural landscape, during my Postdoctoral fellowship at the University of Copenhagen.
My studies leading to this research trajectory were in Ecology, at the University of Cape Town (BSc Hons) and at the Université de Montpellier (MSc).
