I am an entomologist interested in freshwater diversity and conservation with a focus on dragonflies and damselflies. In addition I work on the terrestrial fauna of Aruba-Bonaire-Curacao and coordinate work on image and sound recognition.

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.
Together with over twenty volunteer specialists I work on on the terrestrial fauna of Aruba-Bonaire-Curacao. We aim to describe the diversity on these islands and make information on identification available through papers, field guides and image recognition.
In addition I coordinate part of the work on image- and sound recognition going on at Naturalis. For this I cooperate closely with collegues at Naturalis and the team of Observation.org. Our shared aim is to make “Image - and sound recognition services available for all European species which are annually used by over a 100.000 citizen scientist resulting in millions of high quality recordings.”
A selection of the topics I am currently working on.
