He is a flexible team player who worked in various international multidisciplinary teams in various countries, e.g. The Netherlands, Germany, Poland, Kenya, Bolivia, Rwanda, Yemen and Iran. He has managed, co-organised and participated in complex projects, field campaigns and research projects and teaching modules for various companies and organisations. Remco is a member of the strategic advisory board of the Erasmus Mundus geoinformation course and the SWOT (Surface Water Ocean Topography Mission) workgroup.


Ruben Goudriaan

Ruben graduated with a MSc degree in Physical Geography from Utrecht University in 2010. In 2007 he attained a BSc degree in Earth Sciences from the same university. His BSc thesis focused on soil water repellency induced by Mediterranean forest fires. During the MSc phase Ruben focused on the use of remote sensing for investigating natural hazards like drought and salinization. His graduation research was part of the geoarchaeological Zakynthos Archaeology Project (Greece) and clarified the relation between erosion/deposition and the distribution of archaeological material on the island. Ruben built an ArcGIS based version of the Morgan-Morgan-Finney erosion/deposition model to predict soil transport in the research area. As part of his internship at the Hoogheemraadschap of Rijnland (Dutch water board) Ruben localized salt water seepage locations in the Haarlemmermeer-polder. He investigated new methods of localizing these salt water springs using satellite, thermal and aerial imagery.


Rutger Kassies

Rutger graduated from Windesheim College (Zwolle) in 2007 with a specialization in Computer Informatics and Management & Organizations. Before joining eLEAF, Rutger built up agricultural working experience at Agrifirm, where he held the position of TeamLeader Cereal Laboratory. Rutger has a strong interest in meteorology, which prompted him to combine his hobby with a professional position in the field of agro-meteorology and crop growth predictions.


Annemarie Klaasse

Ir. Annemarie Klaasse is a remote sensing expert interested in projects addressing the allocation and management of water resources among competing water sectors and of land uses in river basins.
