Academic interests

My research focuses on the sedimentology and geochemistry of carbonate rocks to better constrain the initial rise of atmospheric oxygen. I am currently working on recently acquired Paleoproterozoic drill cores from Gabon within the framework of GOE-DEEP (Gabon and Oxygenation of Earth – Drilling Early Earth Project). My research interests also include the geochemical behaviour of rare earth elements in aqueous environments and shock deformation features in impact craters.
