Dr Freymueller studies active crustal deformation processes; the kinematics and dynamics of the active processes that shape the Earth. His active research projects include studies of tectonic deformation in plate boundary zones, earthquakes, postseismic deformation and the earthquake cycle, inflation and eruption of active volcanoes, glacial-isostatic adjustment and its effects on relative sea level, and variations in water, snow and ice via the deformation these load variations cause.
