About me

Volcanologist at KNMI, 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. 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. As part of these experiences, I gained skills in mapping volcanic deposits (including active lava flows), measuring a variety of geophysical signals (magnetic, gravity, electrical conductivity, and very-low frequency signals), collecting and interpreting deformation data (primarily GPS, levelling, and tilt), and analysing seismic data. I applied this broad skill set to my PhD research on restless volcanic systems in Iceland, 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.
