Research Interests

The focus of my research program is to study deformation of the solid Earth–in particular exploring the complex dynamical couplings between convection in the mantle, tectonics in the crust, and surface processes controlled by the atmosphere.  Broadly, the goal of the work is to determine the driving forces for lithospheric tectonics on the active surface of the Earth and other planetary bodies.

The research program is characterised by a cross-disciplinary methodology where computational models of mantle-crust-climate processes are used in conjunction with geophysical, geological, and geodetic observational constraints.

The geodynamics research relates to a variety of tectonic regimes that span Earth’s history from the Archean to present-day.  Specific areas of study include:  tectonics of Canada’s high arctic; active continental collision across South Island, New Zealand; slab retreat and overlying orogenesis of the Apennines belt in Northern Italy; lithospheric delamination beneath Eastern Anatolia; and mantle-crust interactions on Io.
