Research interests

The beauty of geochemistry (to me) is its versatility as a tool for studying large-scale processes on Earth and in the early Solar System. In my opinion, the core of this tool is formed by the development of new analytical methods and strategies in the lab, whereas the scientific disciplines to which these methods are applied are only constrained by the method's borders. Some of my favourite fields that I am chasing in the lab are:

  • Mass-independent isotope variations (O, S, Cr, Hf, W, Pt) in early solar system materials as tracers for the transport and processing of presolar dust and early solids in the protoplanetary disk

  • Triple O isotope variations in igneous and metamorphic rocks as tracers for impact contamination, planetary accretion, hydrothermal alteration and magma mixing processes

  • Interactions between the Archean atmosphere, hydrosphere and lithosphere

  • Half-life determination of long-lived radionuclides (184Os, 190Pt) using natural materials

  • Amphibole compositions in igneous systems and H isotope fractionation during amphibole dehydration/dehydrogenation

The ultimate hardware toolkit for studying these fields consists of multi-collector ICP-MS, TIMS and gas source mass spectrometry, but also of optical microscopy, electron microprobe analysis and Mössbauer spectroscopy.
