I am an entomologist interested in freshwater diversity and conservation with a main focus on dragonflies and damselflies.

Freshwater habitats such as rivers, brooks and lakes are among the most attractive landscapes our planet has on offer. Although these habitats are on a global scale relatively scarce, they are nonetheless of vital importance for biodiversity. Climate change combined with the ever-increasing demand for fresh water by humans will put severe pressure on the biodiversity of these habitats. My work aims at describing and understanding patterns and changes in freshwater biodiversity. I do so by working on the taxonomy, distribution and phylogeny of the most beautiful of all insects: dragonflies and damselflies.
In addition, I work on facilitating the work of citizens scientist and volunteer experts by contributing to the development of image- and sound recognition and by organising citizens scientist expeditions.
A selection of the topics I am currently working on.
