My research is focused on earthquake physics, including rupture nucleation and mechanics, stress-triggering, and fault dynamics and structures. In collaboration with Tom Jordan, I have focused my efforts on investigating micro-earthquakes in South African gold mines recorded at distances as little as 10 meters from the source. I am exploring the data set for trends in stress scaling implications as well as comparisons with predictions from rate- and state-friction laws. I also have interests in intermediate-depth earthquakes and the mechanical properties of fault gouge.
