Research Interests

My research interests place me within the Deep Earth Research Group of the Institute of Geophysics and Tectonics. My primary research focus is the dynamics of the core-mantle system. Observed oscillations of the fluid and solid cores provide insight into properties such as the strength and morphology of the magnetic field within the core, the viscosities of the fluid and solid cores, the shape of the inner core and core-mantle boundaries, and the conductivity of the lowermost mantle. Core oscillations can be detected using observations of magnetic field variations, changes in length-of-day and polar motion, and changes in the gravity field. The global magnetic field is generated by fluid motions in the core, and by studying the structure and evolution of the magnetic field we can understand the dynamics of the core and its interactions with the overlying mantle.

Current PhD Students I am (co)supervising:
Ben Todd
Maurits Metman
Sam Greenwood
Robert Long

Past members of the group include:
Dr Will Brown now at the Britsh Geological Survey, Edinburgh
Dr Grace Cox now at the Dublin Institute for Advanced Studies
Dr Luke Jackson now at the University of Oxford
Dr Luis Silva now at Ubiquis Consulting

Teaching Interests

My Deep Earth research interests contribute directly to my undergraduate teaching in undergaduate modules and research projects.

I also teach methods such as gravity, magnetics, electromagnetics, resistivity, and GPR in undergraduate and master's modules. I participate in a range of both geophysics and geology field trips.


We live on a fascinating planet in an amazing universe, it's what I study and I'm keen to share my interest.

Phil Livermore and I wrote a piece for The Conversation on Why the Earth’s magnetic poles could be about to swap places – and how it would affect us

I have presented on the Earth, planets, and magnetic fields to: the Pint of Science festival, Leeds City Museum Cafe Scientifique, Cumberland Geologocial Society, Astronomical Society of Glasgow, Geological Society of Glasgow, Leeds Geological Association, Manchester Museum of Science and Industry, and various regional schools through the Junior Cafe Scientifique program.

I occasionally tweet about deep Earth geophysics stories that catch my eye, you can follow me @ChthonicJon
