My research focuses on the tectonic evolution of the circum-Arctic. I have done extensive fieldwork in places such as Svalbard Archipelago in Norway, Ellesmere Island in Canada, or east-central Alaska. I combine modern stratigraphy and provenance analyses with deformation dating to investigate complex tectonic boundaries. My work is always grounded in geologic mapping and extensive fieldwork with the application of geochronology, thermochronology or stable and radiogenic isotope geochemistry applied to both sedimentary and igneous rocks.
