RESEARCH TOPICS ADDRESSED:

• Rheology of the Earth mantle;
  
• Geophysical phenomena and geodetic observations related to global geodetic reference frames;
  
• Monitoring, analyzing variations, and modeling physical parameters of the Earth system from global to local spatial scales and temporal scales from minutes to millenia, including, but not limited to Earth rotation, displacements of the Earth surface, fluxes in the global water cycle, sea level, atmospheric water content, air pressure, temperature, wind, etc.;
  
• Sea level fluctuations and global climate change;
  
• Earth rotation studies and integration of the solid Earth into Earth system models;
  
• Deformations of the Earth due to exogenic forcing, particularly postglacial rebound and atmospheric, oceanic, hydrological and cryospheric loading;
  
• General approach to studies of the Earth system;
  
• Inproving the global geodetic reference frame as a major utility for all Earth observation;
• Application of geodetic techniques to geohazards and early warning.
