I study the geochemical composition and flux of mineral dust transported to polar regions and preserved in the ice core record. I aim to answer questions related to how dust flux and sources vary over major climate transitions, and its role in the iron fertilization of marine phytoplankton. I am also interested in probing how changing Earth surface conditions can alter sediment fluxes and bioavailable nutrients during source to sink transport.
