Stefan Maus is a Senior Scientist at the University of Colorado. As the Geomagnetism Team Lead at NOAA’s National Geophysical Data Center from 2004 to 2013, he supervised the production of the World Magnetic Model generations 2005 and 2010 and developed the first High Definition Geomagnetic Model. He received a BSc in Mathematics in 1988 and a MSc in Geophysics in 1993, both from the University of Munich (Germany), followed by a PhD in 1997 at National Geophysical Research Institute in Hyderabad (India). After a Post-doc in Leeds, he taught Geophysics at the University of Braunschweig and at Free University Berlin. From 2000-2004 he was the specialist for crustal magnetic fields in the CHAMP satellite team at GeoForschungsZentrum Potsdam. Stefan continues to be involved in magnetic satellite missions, in particular as member of the Validation Team of the Swarm satellite mission of the European Space Agency. His primary interest lies in Geomagnetism, with a focus on producing magnetic field models for research and navigation from satellite, airborne and marine magnetic measurements. Stefan has authored and co-authored more than 100 peer-reviewed publications. In 2010, he founded Magnetic Variation Services LLC to provide specialized geomagnetic field services to the oil and gas industry.
