Education :

Ph.D. : Caltech, 1987
Undergrad : Yale University, double major in physics and geology, 1981
Background :

After 25 years in California for grad school, working at UC Santa Cruz, the USGS in Menlo Park, and UCLA, I finally escaped to the verdant Northwest last summer.

Current Research :

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.
Graduate Students :
  • Andrew Delorey
  • I'm looking for one or two more
