Research interest

I am fascinated by the sophisticated strategies and structures plants and fungi have developed to interact with each other - either as parasites or pathogens or as partner of a symbiosis.

For my PhD I joined the Stukenbrock lab and changed from mutualistic (arbuscular mycorrhiza) to plant-pathogen interactions.

Our model the Zymoseptoria species complex provides us a unique opportunity to study the influence of adaptive evolution on three very closely related grass pathogens. Although these pathogenic fungi share a common origin in the Middle East they are adapted to different host grasses and ecosystems.

I conduct microscopic analyses to dissect how the Zymoseptoria species spread and propagate in the leaves of their hosts. Furthermore, I relate descriptive microscopic date to stage-specific fungal transcriptomes and perform comparative analyses. The goal is to identify functional and phenotypic traits of the infection process that have been affected during the speciation and host specialisation of Z. tritici. We aim to discover key features that led to the divergence of Z. tritici and allowed it to specialize to wheat and adapt to an agro-ecosystem.
