Anny Cazenave

Anny Cazenave holds a PhD in Geophysics from the University of Toulouse, and is a distinguished engineer of the French National Center for Space studies (CNES). She is currently Director for Earth Sciences at the International Space Science Institute (ISSI) in Bern, Switzerland. She has been a member of the French Academy of Sciences since 2004 and of the National Academy of Sciences (USA) since 2008.

Her research interests include the application of space techniques to geosciences, mainly focusing on the following topics:

  • Satellite geodesy and space research in Earth sciences : Gravity field and marine geoid;
  • Earth rotation and polar motion;
  • Tides;
  • Precise positioning by space geodesy techniques and applications related to tectonic motions, vertical crustal motions, geocenter motions;
  • Temporal changes of the Earth’s gravity field and global mass redistributions among the surface fluid envelopes of Earth (oceans, atmosphere, land);
  • Sea level variations at regional and global scales (observation from satellite altimetry and tide gauges; study of climatic causes: ocean thermal expansion and salinity effects, mass balance of the ice sheets, land water storage change, etc.);
  • Water cycle and land hydrology from space;
  • Climate research.


She dedicated a part of her career to researching spatial and temporal variations of gravity, before focusing in the 90’s on space oceanography. Through data recorded by satellites Topex/Poseidon, Jason-1 and Jason-2, Anny Cazenave has addressed the issue of global sea level rise. She is a member of the Intergovernmental Panel on Climate Change (IPCC) and the lead author on the sea level sections of its fifth assessment report.

Anny Cazenave is a member of several national and international organizations, such as the Earth system sciences committee of the European Research Council (ERC), the scientific committee of the World Climate Research Program of the World Meteorological Organization (WMO), the Conseil Supérieur des Programmes of the French Ministry of Education and the Conseil d’Administration of CNRS (Centre National de la Recherche Scientifique). She also is the head of the Scientific Council of MeteoFrance.
