I am a geophysicist who works primarily with geodetic data and numerical and analytical modeling to investigate active deformation of the lithosphere. In particular, I study how deformation within plate boundary zones is accommodated by faulting and folding in the crust and viscous flow in the lower crust and upper mantle.
The types of research questions that motivate my current work and will continue to drive future research include:
