Nils Olsen

Nils Olsen is a Professor and Head of Geomagnetism and Geospace at the Department of Space Research and Technology, DTU Space (Danish National Space Center). His career spans multiple institutions including the Niels Bohr Institute at the University of Copenhagen and the Danish Center for Planetary Science. He holds a MSc (1985) and PhD (1991) in Physics from Göttingen University.

Research interests center on Earth’s magnetic field modeling, core fluid dynamics, electromagnetic induction, and planetary magnetism (Mars, Moon). His work integrates Swarm satellite data, Ørsted missions, and CHAMP observations to study geomagnetic variations and external-internal field separation. Recent publications focus on tidal magnetic signals, ionospheric currents, and space weather applications.

Supervision includes PhD projects on drone-borne magnetic surveying, machine learning for geophysical inversion, and UAV-based near-surface geophysics. Collaborations extend to ESA’s Swarm mission and CSES satellite initiatives, with over 100 peer-reviewed publications and leadership roles in international geophysical working groups.
