Research Direction

My research focuses on active and neotectonic deformation in the shallow crust at plate boundaries. Areas of particular emphasis include: seismotectonics; inverse modeling of seismicity and geodesy; kinematic analysis of outcrop-scale features; accretionary wedge deformation; and fault:fluid interactions.
