R&D Weather and Climate Modeling

About me

At KNMI I have multiple roles. The main one is climate researcher in climate analysis: using observational and model datasets to investigate how the climate is predictable due to climate change, but also due to El NiƱo and decadal variability, with an emphasis on extreme weather and climate events. This often comes together in Extreme Event Attribution: estimating the role of anthropogenic climate change on extreme events. Besides this I also maintain the data and software of the Climate Explorer climate analysis web site, and try to communicate results from climate research to the public. Since October 2019 I am also visiting professor at the University of Oxford.


I work on various EU-funded and KNMI-funded projects and participate in the (currently unfunded) World Weather attribution (WWA) collaboration.
