GPS measurements of postglacial rebound from Project BIFROST (Baseline Inferences for Fennoscandian Rebound Observations, Sea level, and Tectonics) [Lidberg et al., 2007].

The focus of my research is geodesy, the science of measurement of the size, shape, rotation, and gravitational field of the Earth. I specialize in acquiring, analyzing, and interpreting space-based geodetic measurements. A variety of processes can influence geodetic measurements over a range of spatial and temporal scales, including:

  • Postglacial rebound;
  • Crustal motion associated with plate tectonics, earthquakes, and volcanos;
  • Tides of the solid Earth and the oceans;
  • Changes in sea level;
  • Weather and climate, and atmospheric structure and dynamics;
  • Hydrology and continental water storage;
  • Mass fluctuations and motions of glaciers and ice complexes;
  • Ocean and atmospheric circulation.

I also engage in the research and development of technology aimed at the improvement in accuracy of space geodetic systems and techniques.
