Background and activities

My research is focused on understanding the fundamental magnetic properties of rocks and minerals, and how the atomic-scale properties affect magnetic anomalies on local, regional and satellite scales.  My projects and funding, have ranged from nanotechnology through mineral resource investigations to space-research programs. I received my PhD in 1993, and have over 80 publications in the international journals in the fields of rock and mineral magnetism, crustal magnetism, exploration, mineralogy, petrology and geochemistry. My research is highly interdisciplinary and my co-authors are in the fields of physics, chemistry, nanomaterials, crystallography and geophysics. In 2009, I gave the Bullard Lecture at the American Geophysical Union on the subject of Crustal Magnetism. I have given over 50 invited international lectures at international conferences and at universities around the world. 

In 2012, I moved to NTNU from the Geological Survey of Norway, where I was a senior researcher.  Since moving to NTNU I have built up a program focusing on the magnetic behaviour of crustal rocks at all scales (atomic to satellite) with 2 postdocs, 3PhDs, 4 masters students working on these topics.

I was a chair of the Advisory Board for the Institute of Rock Magnetism, University of Minnesota, USA. I am member of Det Kongelige Norske Videnskabers Selskab (The Royal Norwegian Society of Sciences and Letters), Norges Tekniske Vitenskapsakademi (Norwegian Academy of Technical Sciences), a Fellow of the Mineralogical Society of America and the Geological Society of America. Board member of the Deep research School (UiO) and National Geomagnetism Laboratory at UiO.
