My day-to-day research consists of a combination of numerical or analytical and observational work.  Most recently I have been combining seismic and geodetic observations with models of frictional faults, with the goal of improving our understanding of the various styles of fault slip in the Earth.  In the case of episodic slow slip and tremor in subduction zones, this has meant targeting the numerical models and observations to distinguish between the various mechanisms that have been proposed to explain them.  In a previous life I used a similar combination of numerical models and observations to address dike propagation in volcanic regions; periodically I get tugged back in this direction.
