My research activities focus on efforts to develop an improved framework for the physics of earthquakes and faults using a variety of theoretical tools and observational results. Examples of current research interests include dynamic ruptures and seismic waves in fault structures with bimaterial interfaces and geometrical heterogeneities, damage rheology for irreversible brittle deformation, material fragmentation and pulverized fault zone rocks, dynamics of avalanches in granular materials, high resolution imaging of fault zone environments, analysis of earthquake source properties, and correlations between spatio-temporal seismicity patterns and properties of fault zones (e.g. bimaterial interfaces) and the crust (e.g. heat flow). See Publications for recent papers on these topics.
