Overview of Research

I am a Research Associate Professor and Facility Manager at the Institute for Rock Magnetism, Department of Earth and Environmental Sciences, University of Minnesota. 

I am interested in how magnetism can be applied to understand the Earth. My main research focus is on variations of Earth’s magnetic field through geological time, from recent changes on archaeological time scales, to reversals and excursions, to its long term evolution. Laboratory measurements of the past direction and strength of the geomagnetic field recorded in rocks and sediments 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.

I am the current custodian of the GEOMAGIA50 database, which contains paleomagnetic, rock magnetic and chronological data obtained from archaeological artefacts, volcanic rocks and sediments covering the past 50 ka, and the ICEPMAG database, which houses all palaeomagnetic measurements made on Icelandic lava flows. 

I am an editor for the journal Earth, Planets and Space.
