Her research focuses on the formation of mountain ranges and the mechanisms involved in subduction zones. In particular, she and her students study the metamorphic reactions, geochronology, and deformation of ultrahigh-pressure rocks from Western Norway to better understand the tectonic history of the Scandinavian Caledonides.
