My research focuses on single crystal and whole rock geochemical analysis. This covers the tracing of hydrothermal processes in the context of brittle-ductile tectonics during orogenic evolution, as well as of magmatic activity in the continental crust. I am currently involved in the study of Palaeoproterozoic quartz veins in Greenland, the timing of partial melting processes in the Moldanubian Batholith, as well as the recalibration of the quartz-monazite oxygen isotope thermometer.
