I study material properties under high-pressure and high-temperature 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.
