My research passion is using geophysics to solve problems in hydrologic science and sustainability. My current focus is the use of geodetic measurements of surface deformation, especially InSAR, to further groundwater science and management. This research area includes the study of land subsidence, a major hazard caused by overextraction of groundwater, and groundwater storage changes. My approach is to use analytic and numerical modelling alongside remote sensing and in-situ data to answer questions such as: What is the link between groundwater levels and subsidence? How can surface deformation observations be used to constrain groundwater storage changes? How are we able to monitor subsidence today and in the future?
