Research Interests
Space-time characteristics of earthquakes, Seismic Hazard calculations, seismic imaging of crustal structure, stress interactions between volcanic and tectonic regimes.

My current research has focused primarily on 1) modelling the interaction between the volcanic system at Yellowstone with the surrounding large normal faults including the Hebgen Lake fault, site of the 1959 Ms 7.5 Hebgen Lake earthquake and 2) local earthquake tomography of the upper crust of Yellowstone.
