Profile
Senior research scientist within the use of satellite altimetry and other remote sensing data for geodetic, geophysical, oceanographic, climatological and hydrological purposes. I have a masters in geophysics and a Ph. D. focusing on ocean tide modeling from the University of Copenhagen. I am a member of the science working teams associated with the NASA-CNES TOPEX/POSEIDON, JASON-1 and GRACE satellite missions. Assistant secretary general within the International Association of Geodesy and member of several international study groups within the field of satellite altimetry and board member of the IAS. I participate in numerous national and international projects and worked during 1998 as guest scientist at the CSIRO Marine Laboratory and the Antarctic Commonwealth Research centre in Hobart, Australia, and during 2004 at NASA - GSFC. Currently I am project leader on the National Danish research project HYDROGRAV on the use of gravimetric methods for hydrology.Expertise related to UN Sustainable Development Goals
