Research Profile:

I am a marine geochemist, with experience in trace-element geochemistry and paleoceanography of the Southern Ocean.

My current project focuses on reconstructing ice-volumes and weathering using a multi-proxy record (δ18O, Mg/Ca, Nd and Pb isotopes) during the late Oligocene, to better understand the variability of the Antarctic ice-sheet in a world that is warmer than today.
