I have focused my research on the mechanics of earthquakes and faulting using an interdisciplinary approach that integrates geological, geophysical and experimental observations on earthquake processes. For me there is much learn by considering phenomena at the boundaries between different disciplines. Applied/unconventional aspects of my research include CO2 sequestration, oil/gas reservoir characterization and the mechanics of induced vs. triggered seismicity.

These activities have afforded me a very solid yet unusually broad scientific experience in the field of the mechanics of earthquakes and faulting demonstrated by:
