Research Overview

My research passion is using remote sensing data to solve problems in hydrologic science and sustainability. My current focus is on the use of Earth observation data to improve our quantification of the fluxes and stores in the hydrologic cycle, with a focus on several sub-regions as part of the TRANSCEND project (https://cordis.europa.eu/project/id/101084110; see map below for sub-region locations). I have an additional interest in the use of surface deformation measurements, especially InSAR, for the study of land subsidence, a major hazard caused by groundwater overextraction.
