My research uses geodetic imaging techniques, field surveys and numerical inverse modeling to understand problems in active tectonics and hydrology. Specifically my research involves understanding how faults release strain throughout the earthquake cycle from the surface to upper mantle depths, and changes in terrestrial water storage following major precipitation events (e.g., hurricanes).

I am interested in developing InSAR, GPS, lidar differencing, and optical image correlation techniques with field-based surveys to measure processes ranging from multi-segment co-seismic ruptures, aseismic transients, and post-seismic afterslip to viscoelastic relaxation.

I am particularly interested in understanding the mechanics of near-field, co-seismic surface deformation, and how new and emerging geodetic datasets (e.g. optical image correlation and lidar differencing) inform us about tectonic processes at depth.
