When and under which circumstances does evolution repeat itself? Evolution is driven by a combination of deterministic forces and stochasticity, whose relative importance, however, remains a matter of debate. Knowing how predictable is evolution can provide insights into predictive evolution of crops, pathogens or species under climate change.

This project will address mechanisms driving convergent genome evolution in natural environments. By leveraging fascinating natural diversity of European Brassicaceae which repeatedly adapted to exceptionally strong selective pressure, toxic soils called serpentines, the project aims at uncovering general mechanisms determining which portion of genome evolves in a predictable manner. The successful candidate will conduct extensive sampling of 13 Brassicaceae species in the Balkans, perform controlled common garden experiments and will be involved in population genetic analyses of genome-wide data. We will build on our previous research in wild Arabidopsis but the project will extend beyond this system in order to discern generality. 

Strong motivation for evolutionary biology and independence is a requirement, previous experience with intense fieldwork, experiments and/or population genomic analysis is beneficial. The student will join an established international team of Ecological Genomics at the Department of Botany and the position will be funded by a highly selective Junior Star project.
