Current Research Interests:
Observational global seismology including physics of the earthquake source from broadband waveforms: seismically-radiated energy, relationship to fault mechanics, spatial and temporal details of the rupture process to assess variability and complexity, implications for earthquake hazard. Subduction processes including subduction zone seismicity, physical mechanisms of deep earthquakes and relationship to tectonic processes.
