Research interests

My primary  research interest is the mixing of sediment induced by the macrofauna inhabiting the sediment (i.e. bioturbation). I like to:
- dive deeper into the interactions between macrozoobenthos and their surrounding environment
- understand their driving forces
- take into account the variability on regional and more global scales
- include the effect of global warming (i.e. salinity effect)
- look at the interplay between macrofauna and morphology
- estimate ecosystem services by understanding ecosystem functioning to develop management strategies



About me

I started at the NIOZ Royal Netherlands Institute for Sea Research in April 2017 as a Postdoc. Within the Department of Estuarine & Delta Systems (EDS) I am working with Tom Ysebaert in the Emergo-project ( on Eco-morphological functioning and management of tidal flats. Before that, I did a PhD at the University of Rostock, Germany, Department of Marine Biology on particle dynamics in the sediments of the western Baltic Sea.

NIOZ@SEA | Ecologisch onderzoek in de Nederlandse delta’s
De ecosystemen in de Oosterschelde, Grevelingen en Haringvliet zijn aan het veranderen door de invloed van onze Deltawerken, maar ook door klimaatverandering. In de Oosterschelde verdrinken de zandplaten langzaam door zandhonger, de bodem in het…
