Research on the development of rivers and coasts and their natural systems, and the various services these systems can provide. Hereby, my particular interest is improving our understanding of these systems, so that they can be applied for the benefit of both the natural system and humans.

I received my BSc and MSc at the University of Twente, focussing on water engineering and management. By doing my graduation assignment on “Modelling Consequences of Artificial Structures on Salt Marsh Dynamics in the Wadden Sea” at HKV, I graduated in 2019. After, I started my PhD at the University of Twente, where I am currently doing research on long-term, large-scale estuarine development subjected to nature-based solutions, for estuarine salt intrusion. These nature-based solutions can be either in the estuarine channel (e.g. artificial sand waves) or at its sides (e.g. wetlands or oyster beds). To overcome the various timescales involved in this research, process-based numerical modeling tools will be developed and combined into an efficient framework.

A brief pitch and an article on my MSc thesis project are available below.
