Currently I am working in the research coordination office. I have recently finished and defended my PhD at Leiden University. I'm interested in character evolution (especially of spiders) and, although I do not have a researcher position at the moment, I am happy to help out and co-supervise on student projects.

I'm very interested in studying the evolution of the brain and visual systems in spiders using new generation visualization tools such as micro-CT scanning and immunohistochemistry preparations.
The study of character evolution is not always easy. Traditional microscopic techniques usually require the dissection or thin-slicing of the specimens to observe taxonomically relevant characters. This is especially true for internal anatomy. However, new generation imaging technologies allow us to more easily study and compare internal organs (e.g. Nervous system, digestive tracts, respiratory systems) and external characters (e.g. genitalia, spinnerets, etc.). Providing more informative images with data that can give important insights about the evolution of a taxon. This morphological information combined with molecular phylogenetic analyses offer a magnificent opportunity to trace the evolution of characters and taxa in an unprecedented detail.
