Overview   We have an exciting opportunity available for a Research Associate in Spin Polarisation Physics to join the POLARIS research group in the School of Medicine and Population Health at the University of Sheffield. The successful candidate will undertake research into the physics and engineering of spin-exchange optical pumping (SEOP) used to produce hyperpolarised xenon-129 (129Xe) gas.

The project is funded by an EPSRC research programme aimed at advancing the theoretical and experimental understanding of spin polarisation physics and improving the performance of hyperpolariser systems used in magnetic resonance imaging (MRI). The post holder will investigate the underlying physical processes governing SEOP, including rubidium spin polarisation, vapour dynamics, and spin-exchange interactions with xenon nuclei.

The research will combine theoretical modelling with experimental measurements using optical spectroscopy, magnetic resonance techniques, and newly developed instrumentation designed to probe the dynamics of SEOP systems. The candidate will work closely with physicists and engineers within the POLARIS research group and collaborate with international academic and industrial partners. The work will contribute to the development of next-generation hyperpolariser technology and provide new insights into spin polarisation physics that are relevant to a wide range of applications including biomedical MRI, chemical physics and fundamental spin-based measurement technologies.

Main duties and responsibilities   Conduct experimental and theoretical research to improve understanding of the physics underlying optically pumped spin systems used to produce hyperpolarised xenon gas. Develop and carry out laboratory experiments to study how light interacts with atomic vapours and how this affects the efficiency of spin polarisation. Design and perform optical and magnetic resonance measurements to investigate spin dynamics in alkali-noble gas systems.

Analyse and interpret experimental results and develop models to explain differences between theoretical predictions and experimental observations. Work closely with other researchers in the group to integrate new experimental methods into hyperpolarised xenon production systems. Publish high-impact papers as a lead or contributing author. Present results to project collaborators, members of the research group and external audiences to disseminate and publicise research findings.

As a member of staff, you will be encouraged to make ethical decisions in your role, embedding the University's Sustainability Strategy into your working activities wherever possible. Carry out other duties commensurate with the grade and remit of the post. Person Specification   Our diverse community of staff and students recognises the unique abilities, backgrounds, and beliefs of all. We foster a culture where everyone feels they belong and is respected.

Even if your past experience doesn't match perfectly with this role's criteria, your contribution is valuable, and we encourage you to apply. Please ensure that you reference the application criteria in the application statement when you apply. Criteria Essential or desirable Stage(s) assessed at Good Honours degree in Physics, Physical Chemistry, Engineering or a closely related discipline (or equivalent).
