Personal profile

I have an MSc in Physical Geography from Utrecht University (NL) on slope stability analysis in Colombia (1995) and a PhD in Physical Geography from Utrecht University on the application of 2D flood propagation models for hazard and risk assessment (2007). I currently work at the University of Twente (Enschede, the Netherlands), Faculty of Geo-Information Science and Earth Observation (the former International Institute of Geo-Information Science and Earth Observation - also known as ITC). Within the research group on Natural Hazards and Disaster Risk Management - chaired by Prof. Dr. V. Jetten - I deal with flood related topics. My research interest lies primarily in flood risk assessment in developing countries - with a focus on SE-Asia (Thailand, Vietnam). The focus on developing countries I find particularly interesting because there is (usually) less data to work with, while the need for risk assessment - and appropriate methodologies that can be applied within these specific contexts - is very high.

1995 - 1998After my graduation in 1995 I worked for three years in the private sector as specialist in geostatistics: One year at Witteveen and Bos in Deventer and two years at Gemeentewerken Rotterdam. I applied geostatistics to soil pollution surveys.
1998 - 2001In 1998 I moved to Milan, Italy where I was employed at the University of Milano-Bicocca as junior researcher in the EU-funded research project GETS: Geomorphology and Environmental Impact Assessment for Transportation Systems. In the GETS project I shifted my attention away from the slopes and focused on flood hazard. My study area was the Adige Valley near Trento (Italy) where I applied a two-dimensional flood propagation model to predict the consequences of large scale infrastructural works on the characteristics of (potential) floods in the area. This study became the first case study of three that resulted in my PhD dissertation.
2001 - 2002In 2001 I worked at the Institute of Environment and Sustainability (IES) of the Joint Research Center (JRC) of the European Commission in Ispra, Italy. During my stay I worked on the reconstruction of an inundation of a polder along the Oder River during the 1997 floods. This became the second case study of my dissertation.
2002 - 2003From 2002 to 2003 I was affiliated to the University of Utrecht where I studied in detail the propagation of flood water through the complex anthropogenic topography of the Dutch polder "Land van Maas en Waal". This became the third - and final - case study of my dissertation.
2003 - presentIn 2003 I moved to the ITC, first as a lecturer but since 2007 as assistant Professor. In 2010 ITC became a faculty of the University of Twente.


My teaching focuses on supervision of MSc-students during their research activities, although I contribute to the classroom teaching during the topics "Process Modeling" and "Multi-Hazard Risk Assessment" (see I also give guest lectures at the Asian Institute of Technology in Bangkok, Thailand, at the Post Graduate Institute of Science in Kandy, Sri Lanka, at the Indian Institute of Remote Sensing in Dehra Dun, India and at the Water Resources University in Hanoi, Vietnam. 

ITC hosts also the UNU-school for Disaster Geo-Information Management (see Within that school I coordinate a network of Universities in SE-Asia that collaborate on training and research in the field of geo-information for disaster management. I also contribute to numerous courses conducted in the region.

Research interests

 At ITC my research falls under the chair of Disaster Management (see:, which aims i) at better prediction of Geo-hazards integrating spatial modeling and earth observation information, and ii) at a better integration of socio-economic factors and technical factors in risk assessment and disaster management. My research deals with i) the application of hydro-dynamic models for hazard and risk assessment; ii) developing probabilistic risk assessment methodologies for disaster risk management; and iii) multi-hazard risk assessment.
