Assistant Professor, Department of Water Resources at Twente University in Netherland with a special interest in using geodetic techniques to study sea level and the Earth's water cycle in a changing world. I use techniques and data from satellite observation systems which range from satellite gravimetry, radar altimetry and Global Navigation Satellite Systems (GNSS, which includes GPS). I'm a large proponent of using and leveraging geodetic techniques in interdisciplinary research fields, teaching and capacity building projects.
