Earthquakes and faulting are intricate processes that require multidiscipline approaches to fully characterize the deformation and stress changes. My research is at the intersection of seismology and geodesy and focuses on the seismic response to transient deformation on active faults. Most recently I have focused on surface loading processes as the source of transient deformation. I explore these problems using seismic and geodetic tools to calculate stress changes and explore changes in earthquake rates. Using GPS to estimate monthly water storage, the seasonal stresses from the weight of water indicate a seasonal modulation of seismic activity. To further explore these problems my research is focusing on developing new techniques to detect and locate microseismic events.

Currently, I am a National Science Foundation Postdoctoral Research Fellow at Scripps Institute of Oceanography at the University of California, San Diego and the University of Southern California in Los Angeles working with Yehuda Ben-Zion (USC), Adrian Borsa (UCSD), and Frank Vernon (UCSD). I completed my PhD with Roland Burgmann at UC Berkeley in the Berkeley Seismological Laboratory working on triggered seismic activity from teleseismic earthquakes, fluid injection, and surface loading.
