I am currently measuring the surface velocity field of the northern Basin and Range provinceusing geodetic GPS. In particular, we are interested in how shallow crustal faulting and deeper deformation processes interact to shape the landscape.  Our results should also offer new constraints on slip rates for many poorly constrained faults in the region.

Older work includes a study with Lewis Kogan to evaluate how the large scarp from the 1959 Hebgen Lake earthquake has changed its shape over time. Scarp shape is often used to calculate the age of old earthquakes for hazard analysis, but the standard model can be very misleading for scarps that are hundreds of years old.

I am working with Julie Baldwin on the dynamics of metamorphic core complexes, especially those, like the ones in the northern Rockies and the eastern Pamir, which are associated with collisions between craton and younger terranes. We are moving from 2D mechanical simulations to 3D thermo-mechanical simulations constrained by petrologic observations of pressure, temperature, and time.
