Main research interests:

• The long-term evolution of the Earth's magnetic field (especially in relation to the geodynamo mechanisms and the early history of the field) and its geological and geodynamical implications;


• Geodynamics and global plate tectonics (e.g., large igneous provinces and Precambrian tectonics);


• Applied and environmental geophysics;


• Magnetism of rocks, minerals, meteorites, and synthetic materials and its applications for geological problems;


• Biomagnetism and environmental magnetism (e.g., magnetic signatures of hydrocarbons);


• Development of new techniques and instruments for paleomagnetic and rock magnetic research
