Jasper is a hydraulic engineer with a keen interest in interactions between hydrodynamics, morphology and biology in all kinds of environments. For his MSc-thesis at Delft University of Technology (TUD), he combined fieldwork and numerical modelling to study the effect of riparian vegetation on the development of the Volga River, Russia. During his PhD-candidacy at the same university, he shifted his focus towards estuaries and coasts and got more involved in ecology while working with Radboud University Nijmegen (RU) and NIOZ.
