What we are interested in

We are broadly interested in evolutionary and ecological questions relating to host-parasite and host-microbe interactions. Hence our work encompasses a range of topics including immune defense strategies, emerging infectious diseases, and defensive symbiosis to name a few. Check out our current projects, our publications, and our group members for more.

What we do

We mainly utilise experimental manipulations in laboratory settings but are not shy of sampling in the field combining behavioral observations with immunological, microbiological, chemical-analytical, and molecular methods to span our research from molecules through to the whole organism.

What we work with

Ants our are our main workhorses, but we have lately expanded to other social insects including the honeybee and bumblebees and think that the invasive ladybird beetle Harmonia axyridis is an excellent model organism. Our microbes include a spectrum of bacteria, fungi, and viruses but also the whole host-associated microbial community.
