My research involves deforming, analyzing and modeling various Earth materials at high pressure and temperature to help understand the grain-scale mechanism that govern geological processes such as mountain building and mantle convection.

Phase Equilibria of Quartz under Stress

One of my projects uses high-pressure deformation experiments with a Griggs apparatus, electron backscatter diffraction (EBSD) in a scanning electron microscope (SEM) and Raman spectroscopy and finite element (FE) modeling to understand the stress conditions that form diagnostic ultrahigh-pressure minerals such as coesite (polymorph of quartz) in deformation experiments.

Stress Percolation

Another project I am working on uses similar techniques but focuses on tracking and measuring the movement of grain boundaries using digital image correlation (DIC) to help improve FE models of crystalline materials.
