My research involves striving to improve measurement of land motion using precise GPS processing. Vertical movement is particularly challenging and is important for understanding sea level change and glacial isostatic adjustment. I have worked on higher order ionospheric errors and non-gravitational force effects on GPS orbits. My main current project is working with Antarctic GPS data to produce vertical rates and assess their errors as part of the RATES and REGINA projects.
