Research Summary

My research focusses on understanding deep Earth processes by using high pressure-temperature experiments to determine both geochemical and geophysical properties of mantle minerals. I perform experiments at extreme conditions (several gigapascals) using multi anvil and diamond anvil cell devices, often in combination with synchrotron x-rays or neutron diffraction to investigate geological processes occurring throughout the mantle.

My main interest is understanding the behaviour and influence that volatile species, mostly carbon and hydrogen, have throughout the mantle. Currently I am focused on the role that hydrogen plays in controlling mantle geodynamics, through investigating its affect on the strength of mantle phases.
