Career

In 2016 I obtained my PhD at Naturalis Biodiversity Center/Leiden University. Prior to my PhD I worked at the science departements of Naturalis and NIOZ (Royal Netherlands Institute for Sea Research) as a research assistant and project officer, respectively. I have joined several scientific diving expeditions and performed research in the Caribbean and Indo-Pacific (Curacao, Indonesia, Japan, Malaysia, Republic of the Maldives and Saudi-Arabia). Currently I am a research asssociate at the Marine Biodiversity group.

Research

Research interest

The amazing mimesis of Ovulidae keeps you wondering how it is possible that species look so alike their host corals. Both morphological structures as well as colour are perfectly matched. In the specific case of the ovulid Hiatavolva coarctata, the snails mimick the polyps of their octocoral on its mantle covering the shell. Even more amazing is the fact that they can rectract these polyps like their hosts do, but the mimicked polyps do not have the same function as in the hosts. The ovulid in this example shows an extreme case of camouflage or mimicry. How did such intricate relationships between hosts and their symbiotic (parastic) snails evolve? Does the mimesis have an evolutionary background, which would indicate very species specific interactions, or can alimentary homochromy be the crucial factor? These are the kind of questions that interest me. To have a look for at an overview of the Ovulidae species and there exceptional mimesis, please click here.

Current research topics

The Indo-Pacific coral reefs are considered to be one of the most species-rich ecosystems. Competition for food and space have influenced the evolution of defense mechanisms between species groups. As a PhD candidate at Naturalis Biodiversity Center I study the evolution of parasite-host interactions. To study such a broad topic we have selected Ovulidae (Mollusca: Gastropoda) and Octocorallia (Anthozoa: Cnidaria) as model organisms. With the help of molecular techniques and phylogenetic analyses we try to assess the diversity, plot defense strategies onto cladograms to identify co-evolutionary lineages and to construct models to clarify the evolutionary pathways of species interdependencies in the marine environment.
