I am interested in using continuum mechanics and landscape analysis to understand the physics behind tectonic and climatic interactions. I use numerical models to simulate the translation of strain through the lithosphere to the Earth’s surface, and I take particular interest in how material strength evolves in tectonically active regions, how it influences differential displacement of the lithosphere, and how it influences erosion rate at the Earth’s surface. Our geodynamics research group is currently studying topographic directional dependence, or anisotropy, generated by the exposure of weakened fault zones in actively deforming and eroding regions. We are currently working on simulations that couple tectonic, surface, and atmospheric processes in order to better explore the intricate feedbacks that arise within and between these large systems.


Other interests include ice flow dynamics, sediment transport, thermal stress, fracture mechanics, fractal analysis, homebrewing, and backgammon.
