Dr. E. (Elske) de Zeeuw-van Dalfsen
My early career was marked by time spent working with four different volcano observatories and research centres, including the Hawaiian Volcano Observatory, Nordic Volcanological Institute, Volcanological Survey of Indonesia, and Philippine Institute of Volcanology and Seismology. My PhD research on restless volcanic systems in Iceland, was completed at the Open University in the United Kingdom in 2005. Thereafter, I continued investigations into how volcanoes work as a researcher at the Institut de Physique du Globe (IPGP) in France, the German Research Center for Geosciences (GFZ) and since 2016 at KNMI. One day a week I work on research and teach at the TUDelft.
Volcanologist, tasked with the expansion of the current seismological network with continuous GPS, at the Dutch islands of Saba and St. Eustatius, for volcano monitoring purposes. My goal is to improve the understanding of magmatic processes at active volcanoes with the use of multiple geophysical techniques, such as GPS, InSAR, and micro-gravity. In addition to operations and research, my volcanological experience includes work on hazards assessment and responses to eruption crises.

In the Natural Hazard course I teach a module about volcanoes, their impact on society and how to monitor them.
NEWTON-g aims at developing a field-compatible gravity imager, including an array of low-costs MEMS-based relative gravimeters, anchored on an absolute quantum gravimeter. This system will provide imaging of gravity changes with unparalleled spatio-temporal resolution.
