• Geophysics and fluid flow as it relates to plate tectonics
• Geodynamic modeling of deformation at plate boundaries and within plate interiors.
• 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 squishing?
• How does strain accumulation over the earthquake cycle relate to long-term, geologic deformation?
• What are the implications of laboratory-derived constitutive relations for models of rock deformation?

Most recently, I have been working on how molten aggregates deform and their influence on plate tectonics.
