Exploring Planetary Interiors Experimentally and Computationally


I study material properties at extreme conditions to better understand the constitution and evolution of planetary interiors. My current focus is on combining theoretical ab initio calculations and synchrotron-based diamond anvil cell experiments to better constrain the distribution and cycling of hydrogen in the deep Earth.

I will be moving to Sewanee: The University of the South to join the faculty in the Department of Earth and Environmental Systems in the Fall of 2019.


Ph.D. in Geophysical Sciences, University of Chicago
