He has more than ten years of broad research experience in marine geology and geophysics, particularly related to gas hydrate, shallow gas, geo hazards, continental slope stability, high-latitude sedimentary processes, petroleum systems, CO2-storage, seafloor ecosystems, tectonic and non-tectonic faulting, and the development of sedimentary basins. A great part of his research is aimed to better understand gas hydrate systems, their distribution and their origin.
Stefan holds a PhD degree in marine geology and geophysics from UiT The Arctic University of Norway. He has been an associate professor at the Department of Geology at UiT since 2007. His research contributions are documented in over 30 peer-reviewed publications.
