My research interests focus on how fault structure and small-scale processes affect large-scale fault and crustal behavior. I am particularly interested in the behavior of earth materials in shallow to central crustal conditions, where destructive earthquakes originate and propagate. This research has applications to natural hazards forecast and preparation, energy development, and carbon sequestration. My primary research method is combining structural observations from outcrops and boreholes with laboratory experiments to determine the mechanical, hydrologic, and acoustic properties of different Earth materials, many of them collected from faults worldwide.
