You are the



I am Senior Researcher at PGP (Physics of Geological Processes) at the University of Oslo. I am the scientific coordinator of the Fluid Earth Group at PGP, which involves activities on volcanic processes, CO2 sequestration, and petroleum systems.

PGP was a Norwegian Center of Excellence aiming to bring geologists and physicists to work together in order to get a better understanding of the geological processes. Although the CoE status of PGP ended, PGP activities continue in a group in-between the Departments of Physics and Geosciences.

Outreach paper in Aftenposten Viten


With Anja Røyne, we just published an outreach article in the Norwegian Newspaper Aftenposten Viten on the mysterious 1258-1259 gigantic volcanic eruption detected in the ice cores of Greenlanc and Antartica.

Photograph highlight on EGU Blog

One of the photograph of the Andean Geotrail photograph exhibition has been selected as the image of the week, on the 7th October. The image displays the wonderful petrifying springs of Puente del Inca, Argentinian Andes, at the foot of Cerro Aconcagua (6959 m.o.s.l.), the roof of the Americas.
