Earthquakes, faults, fluids


I am currently a senior research scientist at the University of Wisconsin-Madison, where I run an independent, fully funded research program in earthquake geology. My research draws on aspects of structural geology, paleoseismology, geochemistry, hydrogeology, and statistical analysis to provide quantitative constraints on the physics of recurrent earthquakes, the processes that control them, and their relevant spatial and temporal scales of operation. Although I am primarily a field-based geologist, I am equally at home using experimental and numerical approaches.

This website provides an archive of my research activities as recorded in my publications and CV. If you are having trouble obtaining copies of any of my papers, please do not hesitate to email me ( and I will happily provide them.
