Research interests

My research focus on modern planktonic foraminifera ecology. 

By studying their taxonomy, morphometry, vertical and horizontal distribution, I aim to better constrain their living habitat and the factors controlling it.

Since October 2018 I develop these questions through my own DFG project "Can patchiness explain habitat variability in planktonic foraminifera?" (FoPa).
