I am an environmental scientist who likes to capture the environment in equations and scripts. I enjoy translating my findings for the general audience, policy makers, and between scientific fields. I have a background in environmental sciences, with an emphasis on hydrology and (theoretical) ecology.
I combine dutch air quality data and models to obtain national concentration and deposition maps (GDN/GCN maps). I work with data from luchtmeetnet.nl, with ammonia and nitrogen dioxide data from the MAN network, and with the air quality model OPS. My work includes research on the imputation of missing data, on developing spatial model calibration techniques and on building a better description of dry deposition on vegetation. I also interpret weather- and air quality model output to inform the public in case of a smog event.
I was part of an EU Horizon 2020 project “Marine Ecosystem Restoration in Changing European Seas” (MERCES) in collaboration with various European partners. We developed an indicator framework to guide restoration of coastal ecosystems. This framework was based on spatially explicit models that I developed and analysed. Besides my research activities I lectured at University College Utrecht (UCU) on sustainable resource management, represented post-doctoral researchers in the young scientist representative council of NIOZ-EDS, and supervised MSc students in their graduation projects.
I developed courses and exams, supervised seminars and lectured in the courses of the Bachelor programme Environmental Sciences and the Master programme Sustainable Development. I was involved in the courses Ecosystem Modelling (now Environmental Systems Analysis) and Mathematics and System Analysis.
I established new theory on tipping points in ecosystems by developing and analysing (spatially explicit) models. The focus of my research was on water limited ecosystems and the way these ecosystems cope with the rapidly changing climate. My PhD thesis and associated peer-reviewed publications can be found in the section Publications below. My teaching activities included supervision of students performing scientific research and fieldwork (BSc level), and modelling (MSc level). Besides research and teaching I was PhD representative in the Utrecht Geo Graduate council, organised (guest)lectures in the department, I was minutes secretary of departmental group meetings and co-founded a blog to communicate our department's research to the general audience.
I performed a systematic comparison of a number of global hydrological models for a selection of river basins and wrote a scientific report.
Followed courses on complexity science, theoretical ecology, spatial ecology and academic skills. Attended conferences and workshops on dryland ecohydrology, critical transitions and geosciences.
Graduated Cum laude within the track Earth Surface Hydrology. Followed courses on land surface hydrology, stochastic hydrology, unsaturated zone hydrology, groundwater hydrology, remote sensing and environmental modelling.
Followed courses on hydrology, ecology, soil science, air pollution, landscape ecology, nature conservation, environmental system analysis, environmental modelling, mathematics, physics, chemistry, statistics and academic skills.
