I use the Global Navigation Satellite System (GNSS) and Interferometric Synthetic Aperture Radar (InSAR) data as a tool for measuring crustal deformation before and after earthquakes, in order to constrain physical models that help us to understand how elastic strain accumulates and releases in the crust at different space-time scales, with applications for seismic hazard assessment.
My current research interest include the behavior of the Earth's crust and mantle over long timescales and the way that faults are gradually loaded over time, subduction zone slow slip events, surface displacements and subsidence. In my work, I usually use a variety of satellite and airborne SAR data, Sentinel-1a and 1b, ALOS-2 and JPL’s Uninhabited Aerial Vehicle Synthetic Aperture Radar (UAVSAR) platform.
