The focus of my research program is to study deformation of the solid Earth–in particular exploring the complex dynamical couplings between tectonics in the crust, convection in the mantle, and surface processes controlled by the atmosphere. In particular, these investigations focus on mountain regions and the plate tectonic processes that form them.
The research program is characterised by a cross-disciplinary methodology where geological and geophysical field studies are integrated with computational models of mantle-crust-climate processes.
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 mountain building and volcanism in 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.
