Research and Academic Interests:
Geodynamic modeling of lithospheric deformation at plate boundaries and within plate intetiors.
What can we learn about lithospheric evolution, structure, and rheology from modeling deformation patterns observed at the earth's surface, for example, from geologic and geodetic studies?
How does localized deformation, such as in narrow fault zones, interact with more broadly distributed crustal deformation, e.g. ductile flow? How does strain accumulation over the earthquake cycle relate to long-term, geologic deformation? What are the implications of laboratory-derived friction constitutive relations for large-scale faults at plate boundaries?
Prospective Students
On my personal pages you will find a list of current students and their projects. I am always looking for motivated graduate and undergraduate students who are interested in numerical modeling applied to tectonics. Send me an email or stop by my office for details.
