Research Overview:
My research focuses on the
investigation of
physical processes and properties of the Earths crust, lithosphere, and
upper mantle using measurements, modeling and interpretation of active
deformations occurring over seismic to geologic time scales. I use both
traditional and high-rate GPS geodetic data and seismology to measure
motions associated with earthquakes, intra- and inter-plate
deformations associated with the earthquake cycle and its integration
into orogeny, postseismic deformation, plate tectonics, and crustal and
isostatic responses to variations in crustal loading.

Grad student opportunities
I am seeking two Ph.D. students interested in applying GPS technology
to problems in geodynamics. Both the
POLENET and Patagonian projects have support for a student. These
projects examine the response of the
crust to changing ice loads in Antarctica and Patagonia and plate
tectonic horizontal loads.
If
you are interested, or for more information, please email me.
