My goal is to understand the physics of the earthquake cycle from the time-scale of our lives (tens of years) to the time-scale over which topography is built (millions of years). I use a variety of satellite data sets: GPS, InSAR, optical images, Digital Elevation Models as well as broadband seismic signals to study these processes. 

With observational datasets, laboratory-derived constitutive relationships and numerical simulations, I work to quantify how fault geometry, frictional properties of faults and the rheology of the lithosphere control the earthquake cycle. This multi-disciplinary view is important to determine the seismic hazard in a region, investigate the fundamental mechanics of how the solid Earth deforms, and learn how the landscape that surrounds and sustains us is created.
