I'm a geologist at the University of Oslo, working as a senior researcher at Physics of Geological processes. My research interests include mass extinctions and past environmental perturbations - and the role of volcanism and metamorphism. My main interest besides my work is non-fictional writing. My first popular science book (about natural disasters) was published in Norway in 2006, and was released in the UK in 2009 and Italy in 2010. My second book (Bergtatt / In High Places) was published in October 2011. Topic: The history of mountains.
