Research Summary

My research focusses on understanding deep Earth processes, mostly 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.

I study the role of volatile elements, mostly carbon and hydrogen, on large scale mantle geodynamic processes. I have particularly focussed on chemical and isotopic analyses of natural diamonds and their inclusion cargo to understand how they can inform us about processes occurring hundreds of kilometres beneath Earth's surface. Additionally, by using experimental techniques I seek to determine how properties including the density, acoustic velocities and rheology of Earth and Planetary materials vary in response to changing pressure and temperature conditions.
