“Geoscience may appear to have a geocentric worldview, but it is quite adept in luring you into looking upwards to those other geological wonders in the Solar System.”
Understanding how geological materials and landforms leverage our understanding of planetary evolution is one of my main research interests. This requires the study of extra-terrestrial materials, such as meteorites, and landforms of planetary bodies. Although limited in absolute numbers, the six ‘Dutch’ meteorites tell a fascinating story of primitive, metamorphosed and differentiated planetary bodies, each representing a step in the story (during the first millions of years) of the growth to planethood. However, for the final stages in planetary evolution – spanning the scale of billions of years – landscapes can help us to study and tell this story. Internal and external processes that have affected a planetary surface have caused it to retaining clues to the planet’s geologic, climatic, and possibly biologic past. Where meteoritics studies the earliest rocks, planetary geoscience studies their lasts transformations; both are highly complementary and timely endeavours in the ongoing exploration of our Solar System.
Key issues that I try to address:
- Provide context and possible provenance of the ‘Dutch’ meteorites in the Solar System through spectroscopic characterization of these meteorites and comparisons with spectral types of asteroids.
- Study historic meteorites in museum collections and explore new innovative methodologies to perform compositional and morphological analyses of meteorites using e.g. 3-D and micro-CT data;
- Understand how key physical planetary characteristics, such as gravity or atmospheric conditions, may influence biological or geological processes by using analogue materials, field studies or dedicated laboratory experiments.
- Planetary gemorphology: study process dynamics and infer formative conditions of landforms. Interested in the reworking of sediments by aeolian detachment and transport, and physical weathering of materials by local meteorological conditions.

- Contributed to various news outlets to explain developments in planetary science, space exploration and meteoritics. Notable examples include Klokhuis, RTL Late Night, DWDD, Zapp Live, NOS, Heel Nederland Kijkt Sterren, De Kennis van Nu, National Geographic.
- President of the Royal Netherlands Association for Meteorology and Astronomy (KNVWS), and secretary of its Meteor Section. The latter aims to promote meteor astronomy and contributes to the search and recovery of meteorites, fostering e.g. the Pro-Am collaboration between Naturalis and other groups in The Netherlands.
- Public speaker with a diverse track record, currently focussed on promoting geosciences in the solar system, aiming to cross-pollinate the fields of geology and astronomy. I also contribute to public events at the Naturalis museum to talk about the exciting research that we can do with meteorites.
- My 3D model of the main mass of the 1843 Utrecht meteorite (aka. ‘Blaauwkapel’), has been used by Museum for one day, a social inclusive initiative to bring museum objects and their stories to senior citizens.
- Author of the popular scientific book ‘Praktisch planeetonderzoek voor de zaterdagochtend’ (Lebowksi Publishers, 2016. in: Dutch).
