I study elastic and inelastic deformation of upper plates in subduction zones.

Using thermomechanical models, I simulate long-term slab dip reduction of subduction zones to explain short-term and widespread extensional deformation in the upper plate. Such deformation was observed following the Tōhoku earthquake and other events that produced larger than expected tsunamis. The extensional deformation has been linked to the larger than expected tsunamis that followed these events.

I also use geodetic data to quantify the total deformation of the IndoBurma subduction zone in order to improve seismic hazard assessments for one of the most densely populated regions on Earth.
