Research

I am fascinated by the diversity that organisms display and I try to understand how mutational change translates into phenotypic traits and how evolutionary history can affect this.

I am interested in the role of evolutionary history in the evolution of novel traits. During my PhD I focused on the evolution of phenotypic switching. This new variant evolved in Pseudomonas fluorescens SBW25 during a long-term evolution experiment in the Rainey laboratory. I used the well-established SBW25 model system to perform real-time evolution experiments and used gene reconstruction approaches to investigate how evolutionary history affects the evolution of phenotypic switching. In addition I am interested in repeatability, genotypic and phenotypic parallelism and the role of constraints and epistatic interactions in the evolution of novelties.
