I am an evolutionary ecologist interested in viral ecology and species invasions.
My research combines field studies with molecular tools, phylogenetics, and ecological modelling.
As part of the ERC-funded BeePath project, I study how the introduction of a vector affects viral pathogens in bee communities. Novel transmission routes can alter a pathogen's fitness landscape. The species jump and subsequent spread of the parasitic mite and virus vector Varroa have led to the re-emergence of the deformed wing virus in honey bees, a now highly prevalent pathogen linked to the death of honey bee colonies. As with many RNA viruses, deformed wing virus infects multiple host species including wild bumble bees, although bumble bees are not parasitized by Varroa. We compare honey bee and bumble bee populations from islands that have been invaded by Varroa and Varroa-free islands to study how the introduction of vector-mediated transmission affects pathogen epidemiology and evolution.
I started working on the BeePath project with Lena Wilfert in 2021. Before that, I did my PhD at Victoria University of Wellington in New Zealand with Phil Lester, where I studied the effect of invasive Argentine ants on viral disease in honey bees. I have a B.Sc. and an M.Sc. from the University of Münster. My Master's research project focused on the effect of genetic diversity on fitness in invasive wasps.
