- Turbulence as related to measurement techniques in the atmospheric surface layer, with particular emphasis on scintillometry. In order to understand the observed signal, a thorough knowledge of the underlying turbulent field is needed. This knowledge can be obtained by analysis of observations (tower, aircraft) or by numerical simulation: large eddy simulation for the turbulence on boundary-layer scale and direct numerical simulation for the study of turbulence down to the dissipation scales.
- Turbulence in canopies with an emphasis on scalar transport in and above the canopy. Research is based both on observations and large-eddy simulation.
- Turbulence in the convective boundary layer, with particular emphasis on (dis-)similarities between different scalars. My work focuses on heterogeneity in surface properties and the effect of dissimilar entrainment ratios.
- The practical link between turbulent transport and the surface energy balance. This work encompasses the estimation of the surface evapotranspiration from remote sensing data, land-surface models in atmospheric models and the use of forecasted meteorological data in the prediction of the spread of plant diseases.
- Member of the editorial board of Boundary-Layer Meteorology (since 2010).
- Member of the AMS Committee on Boundary Layer Turbulence (since 2012).
- Authored (together with Jos van Dam, also of Wageningen University) a text-book on 'Transport in the Atmosphere-Vegetation-Soil continuum' , published in 2014 by Cambridge University Press.
- Reviewer of papers for a wide range of journals.
- I developped the rubric for the asssessment of MSc-theses, now used throughout Wageningen University (the rubric and the user manual)
- I co-authored the course module Summer in the City, developed for the secondary school subject Nature, Life and Technology.
- I participated in the development of a simulation tool for secondary school students on the topic of boundary-layer clouds (investigative learning).
- I have been developping a series of low-tech video clips to support my teaching in the courses Atmosphere-Vegetation-Soil Interactions (clips) and Geophysical Fluid Mechanics (clips)
