RESEARCH INTERESTS My current research interests are mostly focused on Quaternary climate and experimental biogeochemistry. My current main interests are: the reconstruction of past variations in the intensity of the Atlantic Meridional Overturning Circulation using (231Pa/230Th)xs,0, the reconstruction of paleo-fluxes in the Pacific using 230Th-normalization, (231Pa/230Th)xs,0 and Pb isotopes as a tracer for terrigenous sediment sources. I have developed an experimental approach to better understand the cycle of Zn, Fe and Cu in surface systems like coccolithophores and seawater and plants and soils.
