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. I am involved with the Space Weather Impacts on Ground-based Systems (SWIGS) project; my contribution involves developing forecasts of geomagnetic field properties that influence the impact of space weather events on the UK.

Student education

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.

Outreach

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 reversals: Why the Earth’s magnetic poles could be about to swap places – and how it would affect us
Chris Davies and I wrote a piece for The Conversation on planetary magnetic fields and habitability: Life on Earth: why we may have the Moon’s now defunct magnetic field to thank for it
Iris van Zelst and I wrote a blog for the EGU Geodynamics blog on: Getting to the core of The Core

I have presented on the Earth, planets, and magnetic fields to: the the University of Leeds Be Curious Festival, University of the Third Age, 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.
