About Me

I am an assistant professor, with an academic background in climate sciences. My teaching and research activities are mainly focussing on climate change services in natural hazard assessment. As the impact of extreme weather events can be huge in our society, we have to prepare, adapt and make ourselves more resilient. At the start of this process is adequate and reliable climate/weather information services. My fundamental interest is how extreme weather data analysis could help a better understanding of natural hazards, like flooding, drought, landslides, flash floods, etc.

Before joining Faculty ITC in 2010, I obtained my PhD at Utrecht Univerisity (2005-2010). My PhD thesis was on the present-day climate of Greenland. Between 2003 and 2005 I worked as a consultant on soil moisture data assimilation at the European Centre of Medium-Range Weather Forecasts, ECMWF, in Reading, UK. Between 2001 and 2003,  I worked on the Dutch wind climate project at the Royal Netherlands Meteorological Institute, KNMI. In 2001, I obtained my MSc degree in 'Soil, Water and Atmosphere', with meteorology as specialization.

My research focuses on the use of weather and climate information services for natural hazard assessment. This work contributes to building a more resilient society to climate change. More specifically, my research interests are:

- Analysis of extreme weather events in a changing climate

- Analysis of extreme weather as a trigger for natural hazards, such as drought, flood, flash floods, etc.

- Advanced use of weather/climate information in Earth science and other application fields, such as food security and water resources

I did my PhD at Utrecht University (2010) on regional climate modelling of Greenland, where my work provided a better understanding of the surface mass balance of the Greenland ice sheet in time and space.

UT Research Information System


As a teacher I am involved in various MSc courses in the M-GEO and M-SE programs, which are mainly international classrooms. My activities involve:

- teaching on climate and weather in various courses

- design and coordination of courses, like the role of geo-information in a changing world, hazard and risk studio, and weather impact analysis

- mentor for students in the Master Spatial Engineering, to provide assistance to students on defining their own learning goals and give them feedback on their personal development plan

- supervisor of students in their BSc/MSc research phase on topics related to climate and weather, mostly in natural hazard studies

Courses Academic Year  2021/2022

Courses in the current academic year are added at the moment they are finalised in the Osiris system. Therefore it is possible that the list is not yet complete for the whole academic year.
