Isotope and trace element geochemistry, biogeochemistry, marine export production, provenance, U-decay series, paleoclimate, paleoceanography.

Our research focuses on the signal transfer between the modern atmosphere and oceans to the geological record, the impact of abrupt events on primary and export production in the oceans, trace element cycles, and reconstruction of Quaternary paleoclimate from lacustrine and marine settings. We combine between time series of modern marine and terrigenous particulate fluxes, coeval seawater compositions, and biogeochemical cycles in the oceans.
