Research interests

I am a PhD student cosupervised by Tatiana Giraud (Université Paris-Saclay, France) and Dominik Begerow (Ruhr-Bochum Universität, Germany). I work on the adaptation of Microbotryum fungi, that are castrating plant pathogens. I study the genomic mechanisms of host adaptation in these fungi and the evolution of their mating-type chromosomes. Fungal plant pathogens are generally highly specialized on their host species. However, host shifts can occur and cause emerging diseases that are a major issue in agronomic systems. Therefore, it is essential to better understand the genomic basis of adaptation in fungal pathogens. In addition, the evolution of mating-type chromosomes is still poorly understood. I am particularly interested in the accumulation dynamics of transposable elements in non-recombining regions of mating-type chromosomes in these fungi and in their genome.
