I am fascinated by the functioning of the natural environment, in particular by sediment dynamics in catchments. I am a soil scientist and geomorphologist by training.
I work on sustainable land use, resilient landscapes and landscape restoration through (innovative) soil and water conservation (SWC) measures and novel landscape design, optimizing the SWC measures within the landscape taking feedbacks between measures into account. I include the effects of climate change and hydroclimatic extremes.
In addition, I also work on the erosion-induced transport of contaminants (pesticides, plastics) within the soil and through the landscape.
I use the concept of hydrological and sediment connectivity, I am particularly interested in how connectivity changes over time and space and how changes in climate and land use affect connectivity, as well as how soil and water conservation measures can dis-connect the sediment and hydrological pathways in the landscape. I quantify connectivity using various connectivity indices.
I use a range of methods, including field investigation, laboratory experiments and numerical modelling. I am experienced in the event-based soil erosion model OpenLISEM, the larger-scale PESERA model, as well as in landscape evolution model LAPSUS.
I have extensive research experience in dryland areas such as the Mediterranean, but also in Ethiopia, Rwanda, Uganda and China. Furthermore, I enjoy collaborating with researchers worldwide, as well as discussing my research at international meetings and conferences.
