My research interests include aspects of igneous and metamorphic petrology as well as geochemistry. Main research themes are:
- Intraplate alkaline magmatism
- Geochronology and element transfer of subduction zone metamorphic rocks
- Light element stable isotopes as geochemical tracers
Past and present field areas of my research are in the Gardar Province (South Greenland), the Raspas Complex (Ecuador), the Coastal Cordillera (Chile), the Lesser Caucasus Volcanic Belt (Armenia) and the Sesia Zone (Western Alps, Italy).
I have served as topic editor for the International Journal of Earth Sciences (Geologische Rundschau) and as Chief Editor for the Journal of Mineralogy and Geochemistry (Neues Jahrbuch für Mineralogie). Since 2020, I am Associate Editor for Geochimica et Cosmochimica Acta. I have also served as committee member and treasurer for the Metamorphic Studies Group, a special interest group of the Geological Society of London and the Mineralogical Society of Great Britain and Ireland.
