Interests 

I am PhD candidate, currently investigating the impact of deoxygenation on the marine nitrogen cycle. Under anoxic conditions, bioavailable nitrogen is lost from the marine system by two microbial processes: anammox and denitrification. By using various tools, including genetic, lipid and isotope work, I hope to acquire a deeper understanding of the various feedback mechanisms between nitrogen cycling dynamics and redox conditions. My speciality is a class of lipids, called 'bacteriohopanepolyols', which can be used as tracers for specific bacteria. Currently, my research focuses on nitrogen cycling dynamics in 1) the contemporary Benguela upwelling system, 2) the Eastern Mediterranean Sea during past anoxic events, 3) the California current system during glacial-interglacial transitions, and 4) the Southern Ocean over the Holocene.

Along the southwestern African continental margin off Namibia and Angola coral mound provinces were found during the Meteor (ANNA) cruise in 2016. While the corals in the south along the Namibian margin were mostly fossil frame structures, the corals…

Off the coast of southwest Africa, currents force cold deep waters full of essential elements required for ocean life to the surface. This so-called upwelling has enormous impacts on the chemistry and biology of the water and sediment. We are sailing…
