About Me
Publications
I'm interested in trying to understand active crustal deformation processes with whatever tools we have at hand, from using satellite-based geodetic measurements of surface motion, to analyzing the past geomorphic record of offsets along individual fault strands with mapping and geochronology. My science journey has allowed me to contribute to the community as both a field-geologist and a geodesist, and having those multiple time-scale perspectives keeps life interesting when the geologic and geodetic worlds collide (a long-standing passion of mine is investigating geologic-geodetic fault slip rate discrepancies).
My current work focuses on using InSAR and GNSS observations to explore earthquakes.
