Using observational geophysics to investigate large and small earthquakes worldwide, I answer outstanding questions about one of the Earth's most devastating phenomenon. Areas of particular interest include microseismicity, seismic sequences, and seismotectonics; fault growth and mechanics; earthquake source physics; ground motion; and real-time hazard monitoring and response. I am also passionote about science communication.
