I use Interferometric Synthetic Aperture Radar (InSAR) time-series
analysis to measure the deformation of the solid Earth's surface. 

By integrating these data with precise Global Navigation Satellite
System (GNSS) measurements, I map spatial and temporal
variations in vertical land motion along urban coastlines in New Zealand and Japan. This information is important for coastal communities who want to better prepare and plan for the ongoing effects of sea-level rise.
