I have an interest in understanding global solid Earth processes, especially ones related to the mantle (the region between the crust and the core). I undertake this research through a combination of numerical modelling and data processing, especially by bringing strong observations to bear on numerical models. The models frequently utilise High-Performance Computing. They have included proposing slab break-off, assessing source region of subduction zone magmatism, subduction zone dynamics, mantle seismic structure, mantle heat flux, mantle circulation modelling, models of mantle dynamics underpinning mantle geochemistry and planetary formation and evolution. I also have a strong interest in supporting early career researchers interested in related research.

I am the School's Director of Recruitment and Admissions. Before that I was the Director of Research, and earlier still I led the Centre for Solid Earth and Natural Resources (2015-16), and l Iead one of its sub-constituent groups, the Mantle Geodynamics Group (MGG) which is part of the Tectonics and Geophysics Research Group.

The Mantle Geodynamic Group tries to understand how the region between the crust and the core, called the mantle, drives Earth dynamics including plate tectonics. We primarily do this using advanced numerical models on high performance computers. We constrain the models using observational data from many disciplines ranging from seismology and geodesy to geochemistry, geology and petrology.

A big project for my group currently is the "Mantle Circulation Constrained (MC2): A multidisciplinary 4D Earth framework for understanding mantle upwellings" grant recently awarded to myself as lead PI, together with a further 13 co-Investigators across 9 UK Universities (see below on the grant section). This project supports a PDRA (Dr. James Panton) who models mantle circulation over the past 1 Ga, focussing on the past 300 Ma. This includes models assimilating plate motion histories provided by Prof. Müller's Earthbyte group at the University of Sydney. The final models will assimilate the seismic tomography structures that will be imaged by the MC2 seismologists working with Dr. Ferreira (UCL) and Dr. Koelemeijer (RHUL). The grant further supports 2 PhD students (Nicolas Récalde and Gwynfor Morgan) in my group who will consider the implications of the mantle circulations models for seismic discontinuities and noble gases. It also supports an isotope geochemist PDRA at Cardiff supervised by Dr. Morten Andersen. In total the project will employ 10 PDRAs across the UK and a further Researcher Co-Investigator. The goal of the project will be to understand mantle upwelling, including passive upwelling, active upwelling beneath "hot-spots", and the active upwellings that have punctuated geological history with their extinction inducing Large Igneous Provinces (LIPS). This project started in November 2020.

Recently this has included

  • Understanding lead isotopes from mantle geodynamics (Panton et al., 2022)
  • Global models of water circulation (Price, Davies and Panton, 2019)
  • Assimilation of seismic tomography into mantle dynamic models (Price and Davies, 2018);
  • Maintaining isotopic domains in mantle circualtion models (Barry et al., 2017)
  • Developing a spectral element code for mantle convection (Phillips et al., 2019)
  • Breaking supercontinents (Wolstencroft and Davies, 2017)
  • Module for global modelling of melting and isotope evolution in the mantle (van Heck et al., 2016)

Over the years I have published on


  • Constraining geodynamics with geochemistry (Panton et al., 2022; Barry et al., 2017)
  • Heat Flow (Davies, 2013; Davies and Davies, 2010)
