I use seismic waveforms, typically recorded at or near the surface, to infer physical processes associated with active faulting. Recent interests include earthquake swarms (and associated fluid-faulting interactions) and tectonic tremor. To gain insight into these processes, I have worked to develop new techniques for earthquake detection, source location, and focal mechanism dete
I earned my Ph.D. from Stanford University in 2007, focused on understanding the mechanism of "non-volcanic tremor" in the Nankai subudction 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. From 2010-2018 I was a Research Geophysicist with the USGS Volcano Science Center (California and Yellowstone Volcano Observatories) in Menlo Park, California. I am now a member of the Geologic Hazards Science Center in Golden, Colorado.
I'm working maximize the information we can obtain from seismic records of faulting processes. This information is then combined with other available constraints (e.g. geodetic, geologic, geochemical) to understand what these seismic signals can tell us about physical (tectonic, hydrothermal, and/or magmatic) processes in the subsurface.
