I have conducted extensive research on earthquakes and Earth structure. My recent work includes measuring the damage to faults during earthquakes, striving to understand why earthquake swarms strike, measuring the rotation of the inner core, and showing there is a correlation, albeit very weak, between the occurrence of earthquakes and the ocean tides.
