Species interactions

I’m interested in how species interactions can shape organisms. Both beneficial and harmful interactions (for example host-parasite interactions or symbioses) exert substantial selection pressures and can thus have a profound influence on the evolution of a species. Social insects, due to their social complexity, are especially interesting study subjects because they allow us to analyse the impact of species interactions on different levels of their society. By combining different methods from behavioural observations to genome analyses, I try to make those effects visible.

Environmental influence on evolution

Global warming is driving habitat change and consequently drives a shift in the distribution of species along their environmental optima. Which traits make a species “equipped” for environmental changes? How can we predict the future distribution of a species based on their biology and current distribution? These questions are especially relevant when looking at invasive species that can have a profound impact on other species, ecosystems, and on human and animal health. Here I mainly focus on invasive mosquito species, such as the tiger mosquito and yellow fever mosquito to find out which traits make them adaptable to different habitats.
