I am a geodesist focusing on satellite geodesy and its applications. Changes in Earth’s mass distribution are reflected in its time-variable gravity field, which is measured by the GRACE and GRACE-FO satellite missions. I use satellite gravimetry observations (range-rate data, non-gravitational accelerations, etc) from the GRACE-FO mission and develop processing schemes to enhance science output. Additionally, I am interested in precise orbit determination, and do operational work for JPL's GPS orbit products.
