Welcome!
Thanks for stopping by my website. My recent news, current research projects and publications can all be found here.
I am an interdisciplinary geologist and Lecturer at Imperial College London. The overarching aim of my research is to accelerate progress towards meeting the UN’s Sustainable Development Goals (SDGs) by quantifying the impact of Earth’s internal dynamics on surface processes.
Currently, I am working to shrink uncertainty in projections of future sea level rise by accurately determining ice volumes during past warm periods, as well as present rates of ice loss. I am also developing new methods to narrow down the search space for ‘supergiant’ metal deposits that will be critical for driving the energy transition. This work is building a more complete 4D picture of Earth’s evolution, helping to resolve outstanding geodynamic controversies including the thermochemical structure of the deep mantle, the composition and dynamics of tectonic plates, and the influence of mantle convection on landscape evolution.
If you have any interest in working with me as part of your undergraduate, graduate or postdoctoral research, I encourage you to get in touch.

17th November 2023New paper alert! By correcting ancient shoreline elevation across Australia for mantle-flow-driven vertical motions, we obtain a more accurate estimate of global mean sea level during the Mid-Pliocene Warm Period (~3 million years ago). This new estimate implies that some recent high-end sea-level projections may be excessively pessimistic but is consistent with mid-range forecasts. Many thanks to my amazing team of co-authors---Sophie Coulson, Mark Hoggard, Jacky Austermann, Blake Dyer and Jerry Mitrovica---for all their help!
17th December 2022New paper alert! By reconciling a suite of geodynamic, geodetic, seismic, and geochemical constraints, we show that the basal sections of LLVPs likely contain a 100–200 km thick layer of dense material, whose physical properties are most compatible those expected for remnants of Earth's early crust. We also find that long-wavelength thermal anomalies associated with LLVPs extend no more than 900 km depth above the CMB. Many thanks to Mark Hoggard, Sia Ghelichkhan, Paula Koelemeijer, and Harriet Lau for their help with this one!
