Personal information

I have a PhD in astrophysics and have since worked in Earth science, on atmospheric composition. My main interests are the climate, biosphere and health impacts of aerosol. I work on the interface between observations and models, using one to make sense of the other. 

I am a Dutch national and have worked before in the Netherlands (KNMI), Japan (NICT and University of Tokyo) and England (University of Oxford).


Recently, I studied observational spatio-temporal sampling impacts on model evaluation and showed sampling can introduce large and unneccessary errors. Currently I am intercomparing a large dataset of satellite remote sensing products for aerosol, evaluating AEROCOM models with that same satellite dataset and trying to deduce the source of model errors.

In the past I worked on data assimilation of aerosol, and developed an ensemble Kalman filter/smoother to estimate aerosol emissions from satellite measurements. This system is used by other researchers ( at NIES in Japan and BSC in Spain). Soon I will return to this work as we will upgrade the system to operate with the ECHAM-HAM global model and multi-angle polarisation measurements from POLDER PARASOL.

I am also starting to use WRF-Chem to simulate landscape fires in order to better understand climate impacts of biomass burning aerosol. 



I studied astrophysics at Utrecht University in the Netherlands and obtained my PhD (on oscillations in solar prominences) from that same place.
