Biography

Dan is a Marine Geophysicist with broad interests in the structure, dynamics and slip-behaviour of subduction zones. Dans primary interest lies in using marine geophysical methods to produce detailed images of the Earth’s crust. I integrate these models with geologic, earthquake and geodetic data to investigate the physical mechanisms that control fault slip behaviour.
