About me

I have a background in climate physics, I obtained an MSc in Meteorology and physical oceanography at Utrecht University. After finishing my PhD project on the response of a Norwegian ice cap to climate change, I worked on global glacier models as a postdoctoral researcher. For several years, I was a project leader contributing to international research projects within a consultancy firm. In 2019, I joined the KNMI scatterometer team that produces ocean surface wind fields from satellite observations. I mainly contribute to the delivery of Level 3 ocean surface winds to CMEMS (see Projects). In addition, I supervise student projects on ocean surface winds.


The Copernicus Marine Environmental Monitoring Service (CMEMS) is funded by the European Union. Its aim is to provide public and private users free access to ocean information. CMEMS products range from operational and forecast data for a wide range of physical and biogeochemical quantities to reports on the state of the ocean. KNMI produces Level 3 ocean surface wind products for the CMEMS catalogue as near real-time and climate data records. I contribute to CMEMS wind product updates with new satellites, product extensions and quality improvements and the development of new products.
