My research focuses on a quantitative understanding of plate tectonics, the fundamental paradigm of modern Earth science. Specifically, I study what happens when tectonic plates collide using numerical models, comparing the topography, gravity, and seismic velocity predicted from the calculations with observations from the Earth. The goal is to understand the connection between deformation at the Earth's surface, as manifest by plate motions, and heat flow from the interior of the Earth. These models push the limits of computing and my work also involves improving the computational methods for viscous flow calculations. Three-dimensional calculations of convection in the interior of the Earth and other planets require significantly more computational resources than will be available in the foreseeable future. I have worked on the evolution of the planet Mercury, specifically focusing on the pattern of compressive features and the time evolution of internal deformation. More recently I have been working on the thermal and volcanic evolution of Venus and Mars. I have also been selected as a guest investigator for the Dawn at Ceres Mission.
