Personal profile

Personal profile

Wietske Bijker focusses on monitoring systems based on remote sensing, especially for vegetated surfaces (forestry, nature conservation, agriculture, individual trees). She has an MSc in soil science of the tropics and subtropics of Wageningen University (1990) and a PhD of the same university, on a PhD thesis titled: "Radar for rain forest: A monitoring system for land cover change in the Colombian Amazon" (1997).

Early 1990, she started her career as a researcher at Wageningen University working on the improvement of a model for the growth and water-use of tropical forests. Per October 1990, she was appointed as researcher at the International Institute for Geo-Information Science and Earth Observation (ITC, Enschede, The Netherlands), where she continued to work as an assistant professor, first for the Division of Agriculture, Conservation and Environment (ACE) and since 2002 for the Department of Earth Observation Sciences (EOS). In 2010, ITC became a faculty of the University of Twente.
