Peter Clarke works at the interface of geodesy and geophysics, using precise GPS/GNSS positioning to study the deformation of the Earth due to plate tectonics, tides, and surface mass loading. His interests span the applications of these areas to geohazards such as earthquakes, tsunamis and climate change (changes in the global hydrological cycle, ice sheet mass, and atmospheric water vapour).
