RESEARCH INTERESTS My current research interests are mostly focused on experimental biogeochemistry and on Quaternary climate. I have developed experimental approaches to better understand the elemental and isotopic cycles of transition elements, notably Zn, Fe and Cu, in surface systems like plants and soils or coccolithophores and seawater. My projects on Quaternary climate include the reconstruction of the variations of the Atlantic Meridional Overturning Circulation export using (231Pa/230Th)xs,0 and the reconstruction of paleofluxes (export productivity, detrital and dust) in the Pacific using 230Thnormalization, (231Pa/230Th)xs,0 and Pb isotopes to trace dust sources.
