I am a postdoctoral researcher at the University of Twente and a guest researcher at Deltares, working on the Living Dikes project. Living Dikes are nature-based coastal defense systems that integrate engineered dikes with vegetated foreshores, such as salt marshes. They offer a sustainable alternative to traditional flood defenses by enhancing wave damping while providing ecological and climate-resilience benefits. With climate change driving more frequent storms and sea-level rise, such solutions are becoming increasingly vital. In my current postdoc, I am developing a 3D CFD model of wave-vegetation-dike interactions to investigate the physical processes that govern wave attenuation across vegetated foreshores. Using OpenFOAM, I systematically study how vegetation characteristics and their configuration with the dike influence wave attenuation, overtopping, and sediment transport.
Previously, I completed a 2-year postdoc in the SALTISolutions project (University of Twente and Deltares). There, I developed an Integrated Assessment Model (IAM) to evaluate salt intrusion mitigation strategies and their impacts on key indicators for water management. The IAM was combined with a serious gaming environment to form the Delta Management Game (DMG), a participatory decision-support tool that engages stakeholders and facilitates social learning. The DMG provides Rijkswaterstaat, waterboards, drinking water companies, and other stakeholders with insights into the trade-offs of their decisions regarding salt intrusion.
I hold a PhD in Coastal Engineering within the ShoreScape project, where my research focused on CFD modelling of airflow and aeolian sediment transport around buildings at the beach-dune interface. I developed a 3D OpenFOAM model to simulate near-bed airflow and its morphological impacts (erosion-deposition patterns), accounting for parameters such as building geometry, orientation relative to wind, distance from neighbouring buildings, and elevation on poles.
My expertise includes numerical modelling, Computational Fluid Dynamics (CFD), 3D OpenFOAM modelling, wave-structure interactions, aeolian sediment transport, Integrated Assessment Models (IAMs), and spatial data analysis. I am passionate about bridging science and practice to develop sustainable, nature-based, and collaborative solutions for climate-resilient water systems.
