I am an animal ecologist, interested in the structure of arthropod communities and their responses to environmental change. In my projects I investigate the highly diverse and abundant fauna of soil- and litter-dwelling arthropods and how these communities are shaped by land-use change and global warming. In particular, I am interested how environmental change affects biotic interactions, such as predator-prey interactions, and thereby drives community composition, biodiversity and ecosystem functioning. 
To identify feeding interactions between arthropods, I use metabarcoding coupled with high-throughput sequencing. This approach allows for accurate determination of ingested prey even under difficult conditions, such as when prey is very small. Such I was able to explore the impact of forest management on centipede prey choice or see how temperature and habitat affects feeding of Arctic wolf spiders.
