Dutch PhD-candidate studying the evolution and ecomorphology of symbiotic crustaceans, living in and on tropical coral reef organisms, using CT-scanning and other figuration methods. Additionally focusing on science-communication and teaching.

PhD studyCrustacean Ecomorphology and Evolution
I use natural-history collections, various figuration methods and phylogenetic studies to shed light on the "Ecomorphology", the adaptations of an animal to a certain lifestyle, of symbiotic crabs, shrimp and other crustaceans, living in and on coral reef organisms.
Using the Naturalis crustacean collection, made world-famous by carcinologists like Holthuis, Buitendijk, and De Haan, I hope to shed more light on the evolution of symbiotic crustaceans, mainly focussing on crabs and shrimp. CT-scanning and other figuration methods make it possible to study the adaptations of a crustacean symbiont, living in or on a host organism. The study of these adaptations to fit a certain habitat and lifestyle, called Ecomorphology, can be combined with phylogenetic analyses to study the convergent evolution of obligate symbionts, but also the host switches which might have occurred in the evolutionary history of these taxa.

Science-Communication plays a major role in my scientific career: I started writing for the Natuurwijzer, spend a lot of time on Twitter and wrote press releases for my own publications. In my spare time I like to work on SciComm projects like Through the Ocular, where I highlight a part of the Education-collection of the University of Leiden & Naturalis
