Current Research:

Dr. Grebby's current research interests are focused on the use of satellite, airborne (manned and UAV) and ground-based Earth Observation techniques for the exploration of geoenergy resources and the monitoring of their exploitation. This includes identifying potential geothermal energy resources by mapping anomalous mineral assemblages and surface temperatures, determining key characteristics (e.g., porosity, permeability, fracture density) for reservoir modelling, the detection of hydrocarbon leakages, and InSAR monitoring of ground motion at sites associated with gas storage (i.e., CO2) and energy production.
