My research is focused on earthquake early warning: using observations made near an earthquake rupture to send warnings to people and automated systems before shaking arrives at their location.  Current projects include using GPS data to determine the geometry and slip distribution of earthquake ruptures in real time, creating joint seismo-geodetic real-time earthquake rupture models, using Bayesian analysis to determine whether a report of an earthquake is real or a false alarm, Bayesian model averaging of multiple independent earthquake source models, and contributing to building the information technology infrastructure of the earthquake early warning system for the West Coast of the United States.  Other projects include applying Bayesian methods to geophysical problems, investigating earthquake source processes through kinematic finite fault rupture modeling using seismic and geodetic data, investigating the effects of error sources on geophysical inverse problems, and applying high-performance computing to geophysical problems including the development of the CATMIP (Cascading Adaptive Transitional Metropolis In Parallel) algorithm for embarrassingly parallel Markov Chain Monte Carlo simulation of high-dimensional probability density functions.
