Summary

My research aims to shed light on the structure and evolution of the Earth and planets by studying the structure and properties of matter at extreme pressures and temperatures. To do this I combine micro-fabrication, laser-heated diamond anvil cell experiments, synchrotron based micro- and nano-scale analytical techniques and ab initio computations. Beyond geoscience, I apply these techniques to the phase diagrams and properties of transition metals and mechanical behaviour of engineering materials.

Royal Society University Research Fellowship

The character of our planet was defined by its earliest experiences. The kinetic energy from giant impacts as it accreted by collision with smaller planetesimals, combined with the heat from radioactive decay caused repeated, wholesale melting of the Earth, the segregation of the metallic core from the silicate mantle, and ultimately, the formation of the moon1. The ensuing magma oceans, which may have extended all the way to the core mantle boundary, would have solidified within a few tens of millions of years at most2. Despite being completed within the first few per cent of Earth’s lifespan, these processes had effects on the geodynamics and habitability of Earth that were profound3 and long lasting: after 4.567 billion years of vigorous convection, driving plate tectonics, volcanism and the continual renewal of Earth’s surface, not all traces of this period have been obscured4. Evidence from the fields of geochemistry, geophysics and geodynamics strongly suggest that its signature has been written, indelibly, into the chemical architecture of the deep Earth. The overarching goal of this proposal is to harness technological advances in high-pressure mineral physics, both experimental and computational, to unpick this short but critical period in Earth’s history.
