Are you an ambitious researcher looking for your next challenge? Do you have an established background in computational fluid dynamics or applied mathematics and an interest in applying your skills to understand the dynamics and evolution of Earth’s core? Do you want to further your career in one of the UK’s leading research intensive Universities?

We are seeking a Research Fellow to fulfil a key role in a large team project by designing and implementing major performance enhancements to computer simulations of fluid dynamics and magnetic field generation in planetary cores. You will be based in the Deep Earth Research Group within the School of Earth and Environment at the University of Leeds and work closely with Dr Chris Davies. This work is funded by the Natural Environment Research Council (NERC) Pushing the Frontiers grant “Earth’s Core as a Layered System”.

Modelling fluid dynamics and magnetic field generation in planetary cores is computationally demanding because of the vast range of spatial and temporal scales that must be resolved and the complex non-linear interactions between fluid flow, magnetic field, and the driving buoyancy source. The prevailing paradigm of direct numerical simulation based on spectral methods cannot access core conditions on current High-Performance Computing (HPC) resources and substantial progress seems unlikely in the next decade. This project will consider a range of strategies for enhancing performance of the existing Leeds Dynamo Code, including but not limited to: hyperdiffusion and turbulence closure schemes; alternative time-stepping methods including parallel-in-time integration; utilising GPU capability and implementing automated task mapping across heterogeneous HPC architectures. These performance enhancements will underpin the team’s investigations into the interactions between double-diffusive convection, two phase flows, and turbulence in Earth’s core.

You will have a PhD or be near completion (i.e. the initial thesis needs to have been handed in at the point of application) in applied mathematics, computer science, physics or similar discipline with a strong background in numerical analysis. You will also have demonstrated the ability to conduct independent research and evidence of peer-reviewed publications in international journals.

This post is expected to begin on 1 January 2022.
