   abstract: "My research focuses on the physical processes occurring prior to, during,\
     \ and following earthquakes and volcanic eruptions and their implications in\
     \ observations of ground displacement, strain, tilt, electric and magnetic fields\
     \ using data from state-of-the-art borehole instrumentation. These data show\
     \ the details of aseismic fault failure, preseismic, coseismic and postseismic\
     \ deformation, earthquake nucleation, volcanic deformation and volcanic processes.\
     \ Theoretical modeling of these processes suggests testable physical explanations\
     \ in term of physics of failure, the role of fluids in the crust, strain redistribution,\
     \ and likely properties of fault zone materials. Very near-field data on slow\
     \ slip, earthquakes and dynamic rupture were obtained in fault zones at 3.6\
     \ km depth in South Africa, a few 10\u2019s of meters from earthquakes from\
     \ M=-4.5 to M=2."
