I use seismic waveforms, typically recorded at or near the surface, to infer physical processes associated with active faulting. I often work to understand earthquake sequences, their underlying interactions, and their tectonic implications through analysis of small earthquakes in aftershocks sequences or earthquake swarms.
I earned my Ph.D. from Stanford University, examining the mechanism of "non-volcanic tremor" in the Nankai subduction zone. After finishing my Ph.D., I was a Miller Postdoctoral Fellow at UC Berkeley and a Mendenhall Postdoctoral Fellow in the USGS Earthquake Science Center, where I focused on detecting and understanding tremor beneath the San Andreas Fault. From 2010-2018 I was a Research Geophysicist with the USGS Volcano Science Center in Menlo Park, California, where I initiated new work on earthquake swarms and fluid-faulting interactions in volcanic and hydrothermal regions, including Yellowstone and Long Valley Calderas.
Since 2018, I am a member of the Geologic Hazards Science Center in Golden, Colorado, with a broad research portfolio that includes earthquake sequences and source physics, tectonics, monitoring (detection, location, magnitudes, focal mechanisms), tectonic tremor, and volcano seismology.
