Multicore Fibre Devices for Hyperspectral Endoscopy (URSA PhD Project) University of Bath in United Kingdom

This PhD project at the University of Bath focuses on developing multicore fibre devices for hyperspectral endoscopy, aiming to revolutionize clinical diagnostics by enabling high-resolution, label-free imaging in anatomically restricted regions. Conventional fibre bundles used in endoscopy are limited to basic imaging modalities, restricting the diagnostic information available to clinicians. The project seeks to overcome these limitations by designing and fabricating next-generation flexible fibre probes capable of capturing rich spectral signatures, thus advancing endoscopic diagnostics and improving patient outcomes.

The successful candidate will explore the mechanisms of light guidance in complex fibre geometries, including mode coupling in tapered fibre bundles and wavelength-dependent propagation effects. The research will involve hands-on fibre fabrication using state-of-the-art facilities, as well as the use of tools to taper and modify optical fibres. Candidates will also develop optical setups to characterize fibres and implement computational reconstruction methods to convert raw fibre outputs into hyperspectral images, enabling the detection of subtle changes in tissue structure and composition.

The project offers flexibility to focus on specific aspects of fibre design and fabrication or computational imaging, depending on the candidate’s strengths and interests. Collaboration opportunities with an interdisciplinary team in photonics and engineering, alongside leading clinicians, provide a direct pathway from foundational optical physics to meaningful clinical impact.

Applicants should hold, or expect to receive, a First Class or good Upper Second Class UK Honours degree (or equivalent) in a relevant subject. A master's level qualification is advantageous. Suitable backgrounds include physics, photonics, engineering, or related fields. Non-UK applicants must meet the English language requirement by the application deadline.

Funding is available through a University of Bath studentship tenable for 3.5 years, covering tuition fees, a stipend (£21,805 p/a in 2026/7), and access to a training support budget. Studentships are open to both Home and exceptional International students; however, International applicants should note that funding does not cover relocation, visa, or UK healthcare surcharge costs.

To apply, submit a formal application via the University of Bath's online application form for a PhD in Physics before the deadline. In the 'Funding your studies' section, select 'University of Bath URSA' as the studentship. In the 'Your PhD project' section, quote the project title and lead supervisor's name. Contact the lead supervisor prior to applying and apply early, as the position may close before the advertised deadline.

The University of Bath values diversity and inclusion, welcoming applications from under-represented groups. If you have circumstances that have affected your educational attainment, you are encouraged to mention them in your application.
