My research centres on the behaviour of matter at extreme pressures and temperatures. I use and develop experimental techniques and equipment — including laser-heated diamond anvil cells, large volume presses, optical spectroscopy, and synchrotron X-ray methods — alongside computational approaches to tackle problems that cut across geology, physics, and engineering.

Much of my work aims to understand the interior structure and evolution of the Earth and planets, but I also enjoy applying high-pressure methods more broadly: to the properties of metals and metallic glasses, the synthesis of novel superconducting materials with physicists, and — most recently — biomineralisation in a rapidly warming world with palaeobiologists.

I held a Royal Society University Research Fellowship from 2016 to 2025 and currently lead a NERC-funded project on copper transport in subduction zones in collaboration with UCL, UNLV, and Diamond Light Source.
