Research Interest

I explore research questions regarding earthquake triggering, induced seismicity, seasonal loading, and interseismic deformation utilizing seismic data (e.g. waveforms, focal mechanisms, and seismicity), geodetic data (e.g. InSAR and GPS), and modeling tools. The goal of my research is to quantify stress changes in the crust, explore seismicity rate variations and migration patterns, and fault deformation rates in order to characterize the evolving state of stress on faults and the migration of fluids in the crust.

Community Outreach

EPS Department Coordinator for Bay Area Science in Schools outreach program organized by Community Resources for Science (crscience.org) from 2015-2017. Lead activities for the Berkeley Seismological Laboratory outreach program. Involvement includes developing lesson plans for earthquakes, faulting, earthquake safety, and preparedness for the 6th – 8th grade level. Travel to local middle schools, with a focus on underrepresented communities, and give 1-2 hour lessons with a lab component on earthquake faulting, liquefaction, and safety.
