My research combines rock physics, seismology and geodynamics.
Through field work, experiments and theory, I have studied the interactions of melt migration and deformation and the influences of melt on the mechanical properties of rocks in the deep Earth.
Currently, my work is focused on the interpretation of seismic velocities measured at plate
boundaries in terms of both rock fabrics and melt distribution, towards building more detailed
images of the structure of plate boundaries and the upper mantle.
Such images provide an observational basis for understanding convection and plate motion as the
general mechanism for heat extraction from the Earth.
