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