Research interests
My research focuses on modern planktonic foraminifera ecology and contribution to the biological carbon pump.
By studying foraminifera assemblages (concentration and taxonomy), morphometry, vertical and horizontal distribution, I aim to better constrain their living habitat and the factors controlling it.
I am currently working within the RECEIVER research theme of the Cluster of Excellence > The Ocean Floor - Earth's Uncharted Interface on the contribution of planktonic foraminifera to the export of carbonate and organic carbon to the deep ocean. The research I carry out in this position is a continuation of my previous work (e.g. own DFG project "Can patchiness explain habitat variability in planktonic foraminifera?" - FoPa).
