I am a research specialist in palaeomagnetism at the Institute of Earth Sciences, University of Iceland. I have previously worked at the Helmholtz-Zentrum Potsdam, Deutsches GeoForschungsZentrum - GFZ, the Institute for Rock Magnetism, University of Minnesota and the Geomagnetism Laboratory, University of Liverpool.
I am interested in variations of Earth’s magnetic field through geological time, from recent secular variation, to reversals and excursions, to its long term evolution. I am especially interested in the determination and quality of palaeomagnetic data. Robust directional and palaeointensity data can be used to calculate changes in the full vector behaviour of the geomagnetic field during significant times in Earth’s history and subsequently understand processes that may occur deep within the Earth.
Some of my research focuses on:
(1) The behaviour of geomagnetic reversals and excursions, from observations, empirical models and dynamo simulations;
(2) The compilation and assessment of Holocene sedimentary records and their use in reconstructing the global geomagnetic field during the last 50 ka (DFG-SPP 1488);
(3) Linking the rock magnetic properties of volcanic rocks to the outcome of different absolute palaeointensity techniques, using historical lavas from the island of Fogo, Cape Verde (NSF award 0911683).
