PhD Studentship: Does the Earth magnetic field spin up the polar vortex in the outer core? Coventry University Group in United Kingdom

This PhD studentship at Coventry University Group investigates a fundamental question in planetary science: does the Earth's magnetic field spin up the polar vortex in the outer core? The project is situated within the Research Centre for Fluid and Complex Systems (FCS) and is funded by the Leverhulme Trust, which supports high-impact, original research.

The research addresses the dynamo process responsible for generating planetary magnetic fields, a phenomenon crucial for shielding planetary surfaces and supporting life. Recent evidence points to the existence of an intense polar vortex within the Earth's liquid core, specifically in the Tangent Cylinder region. The project aims to unravel the origin and role of this vortex in the dynamo process, exploring the novel hypothesis that the magnetic field itself spins up large vortices in the polar region, potentially contributing to the Earth's dynamo.

The successful candidate will employ a combination of numerical simulations using advanced magnetohydrodynamic (MHD) models and experimental work with the unique Little Earth Experiment (LEE). LEE is the only device worldwide capable of reproducing and visualising convective flows in the Earth's liquid core, incorporating both rotational and magnetic effects. Experiments will be conducted in FCS's laboratory and at the high magnetic field laboratory in Grenoble, France, utilising some of the most powerful magnets available.

This studentship offers a unique opportunity to develop expertise in geophysical, numerical, and experimental fluid dynamics, and to contribute to the understanding of planetary magnetic fields. The candidate will benefit from comprehensive research training, technical and professional skills development, and access to the Doctoral College and Centre for Research Capability and Development at Coventry University. The project also provides opportunities to build a global scientific network by collaborating with leading experts in the field.

Applicants should hold at least a 2:1 first degree in a relevant discipline, with a minimum 60% mark in the project element or equivalent and a minimum 60% overall module average. Candidates must demonstrate the potential for innovative research and the ability to complete the PhD within 3.5 years. Applications require full supporting documentation, a covering letter, and a 500-word supporting statement outlining relevant expertise and interests.

For further information, prospective applicants are encouraged to contact Professor Alban Potherat. The application deadline is 27 May 2026. Apply via the provided portal to join a world-leading research environment and contribute to advancing planetary science.
