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 the Norwegian ice cap Hardangerjøkulen to climate change, I worked as a postdoctoral researcher on global glacier models. I worked for several years as a project leader at a consultancy firm, contributing to international research projects. 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 and Level 4 ocean surface winds to the Copernicus Marine Service (see Projects). In addition, I supervise student projects on ocean surface winds.


The Copernicus Marine Service is funded by the European Union. Its aim is to provide public and private users free access to ocean information. Copernicus Marine Service 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 and Level 4 ocean surface wind products for the Copernicus Marine Service catalogue as near real-time and climate data records. I contribute to wind product updates with new satellites, product extensions and quality improvements and the development of new products.
