My research focuses on the evolution of microbial genes and genomes.

Many tools from population genetics have been developed in times where not much genomic and genetic data was available. Today we are able to see low-frequency variations in genomic data, sequence the genomes of thousands of individuals even at the level of a single cell and track the occurrence of mutations and genes over time in experimental evolution.

I am working at the interface of these two worlds using mathematical and computational approaches. I adapt and extend the toolset of population genetics to account for findings in the microbial world, like the existence of huge gene reservoirs on the level of populations (the pangenome) or the evolution of CRISPR-cas Systems.
