Currently looking for a PostDoc for early 2027!
I'm interested in mecanisms that shape current biodiversity and its distribution, from micro to macro scales. I'm particularly interested in and sensitive to high-elevation alpine environments.
I am fascinated by life forms that dwell in these extreme environments and by the way life manages to thrive in what are generally considered harsh and inhospitable environments.
Recently, I have become increasingly interested in how the knowledge acquired through our research in evolution, genomics, and ecology can help us preserve biodiversity and, more importantly, serve as a tool in (socio-)environmental struggles.
I am in my third (and sadly last) year of my PhD.
My current research focuses on the phylogeography of high-elevation alpine plants. We aim to revisit the nunatak hypothesis originally proposed by Marie Brockmann-Jerosch in the 1920s. By focusing on specialist species inhabiting siliceous cliffs of the nival belt in the Alps, we test the idea that these taxa survived the Last Glacial Maximum by persisting on ice-free nunataks within the alpine range.
Using an integrated approach that combines population genomics, ecological modeling, and paleogeomorphology, we seek to reconstruct the late-Quaternary history of high-elevation cushion plants, to better understand their persistence in high-alpine environments and the evolutionary consequences of such survival.
