A position exists for a Research Associate to work on the development of stochastic optimisation methods for large-scale tomographic image reconstruction, within the EPSRC project PET++: Improving Localisation, Diagnosis and Quantification in Clinical and Medical PET Imaging with Randomised Optimisation

This project is a collaborative project between mathematicians in Bath and Cambridge, medical researchers and clinicians from Addenbrookes' hospital and GE Healthcare, with support from advisors from UCL, Oxford, Kings College London, University of Helsinki and KTH Stockholm. We build on the insights from our previous research and continue to develop advanced image reconstruction techniques directly tailored to PET imaging applications, putting a strategy in place to ensure that successful methods are adopted widely in healthcare.

We are looking for excellent and ambitious postdoctoral researchers who want to join this research endeavour. Please note that this is part of a wider recruitment for postdoctoral research staff with another post advertised at Cambridge University (more info is available at

The Bath-based researcher will be part of the Numerical Analysis group. Our 13 permanent staff members in Numerical Analysis create a stimulating environment working on topics such as inverse problems, machine learning, optimisation and analytical+numerical treatment of differential equations. We also benefit from the close proximity to other departments and are currently establishing a Centre for Modelling and Algorithms for Data to support synergies between mathematics and computer science.

Duties of the successful candidate include developing and conducting individual and collaborative research objectives, proposals and projects. You will be expected to plan and manage your own research and administration, with guidance if required, and to assist in the preparation of proposals and applications to external bodies. You must be able to communicate material of a technical nature and be able to build internal and external contacts. You may be asked to assist in the supervision of student projects, the development of student research skills, provide instruction or plan/deliver seminars relating to the research area. 

The successful candidate will have, or will be nearing the completion of, a PhD degree in mathematics or a closely related subject. Expertise in one or more of optimisation, inverse imaging problems and variational reconstruction approaches, large-scale computation as well as in biomedical imaging is desired.

The post carries no teaching or administrative duties. There are generous funds available under the project for attending conferences and conducting research visits.  

This post is fixed-term for 3 years, starting on 1 September 2019 or by mutual agreement.

Interviews with short-listed candidates are likely to take place during 17 – 19 June 2019.

Informal enquiries about the role are very welcome and can be made to Dr Matthias Ehrhardt (
