Clare Boothe Luce Assistant Professor of Earth and Planetary Sciences
Accretion, core formation, and composition of the deep interiors of Earth and other terrestrial planets. She combines high-pressure, high-temperature mineral physics experiments with planetary-scale modeling.

Title: Influence of fluid-assisted healing on fault permeability structure
Abstract: Micro-cracks in fault damage zones can heal through diffusive mass transfer controlled by temperature and pressure. The diffusion of pore fluid pressure in fault damage zones...
Episodic Plate Motion and Thermal Structure in Subduction Zones Caused by Slab Folding in the Transition Zone
Abstract: Although most present-day subduction zones are in trench retreat, plate reconstructions and geological observations show that individual margins experience episodes of advancing, retreating or stationary trench motion with time-variable subduction rates. However, most laboratory and numerical simulations predict steady plate velocities and sustained trench retreat unless the slab experiences folding in the...
