“Using museum specimens to reveal past and present patterns of selection”
As for many biologists, my first love for biology started with the fascination for dinosaurs rather than the world of extant creatures. During my childhood, my grandfather introduced me to aquatic biology by teaching me how to fish, which shifted my interest to living vertebrates. This interest was fuelled by the exposure to the vastly diverse wildlife of the African continent and I became interested in the ecology and evolution of vertebrates. During my study biology I was able to combine my love for fish and Africa and was fortunate enough to continue this combination until present day.
During my Bachelor at Leiden University, I gained ecomorphological research experience by conducting an internship at the Integrative Zoology department where we tested the effects of swimming on testis development in European eel. I continued with a Master in Evolutionary and Ecological Sciences by studying the effects op anthropogenic noise on European blackbird song. After spending half a year in Cameroon conducting research on African lion ecology and livestock conflicts at the Institute of Environmental Sciences (CML), I obtained my Masters degree in 2008.
Intrigued by the study system, in combination with with the possibility to use the extensive and unique Lake Victoria cichlids of Naturalis, I started a PhD at Leiden University on the adaptive responses to environmental changes in Lake Victoria cichlids in 2009. After obtaining my PhD in 2014 I continued as a Postdoc in the lab of Ole Seehausen at EAWAG and the University of Bern in Switzerland.
My research interests lie in the evolutionary ecology of vertebrates. More specifically, I am interested in how organisms adapt to (changes in) their environment, how they speciate and how they eventually radiate (or not). During my PhD, I worked on adaptive responses to environmental changes in Lake Victoria cichlids. This project showed that these haplochromine cichlids were rapidly responding to environmental changes by changing their ecology and morphology in an adaptive way.

Current research topics
1. Constraints to speciation
The Lake Victoria cichlids are famous for their extensive and extremely fast adaptive radation which resulted in over 500 species varying in colour and trophic morphology. Cichlid radiations tend to occur in many African lakes and can often be predicted by lake surface area, depth, solar energy and the occurence of sexual dichromatism in cichlid species. However, cichlid radiations also occur in small, shallow lakes while deeper, larger lakes sometimes seem to harbour only one or two cichlid species. One of my current projects is to unravel why some of these East-African cichlid lineages have diversified while others cichlid lineages have failed to do so by using morphological, ecological and genomic approaches.
2. Detecting patterns of selection in preserved specimens
Lake Victoria cichlids have shown to be able to respond to rapid environmental changes in captivity as in the wild. These fish are able to adapt their morphology and ecology within a timespan of 3 years under natural conditions.
