The award:

This project is one of a number that are in competition for funding from the South West Biosciences Doctoral Training Partnership (SWBio DTP). 

About:

The BBSRC-funded SWBio DTP involves a partnership of world-renown universities, research institutes and industry, based mainly across the South West and Wales.

This partnership has established international, national and regional scientific networks, and widely recognised research excellence and facilities.

We aim to provide you with outstanding interdisciplinary bioscience research training, underpinned by transformative technologies.

Programme Overview:

You will be recruited to a broad, interdisciplinary project, supported by a multidisciplinary supervisory team, with many cross-institutional projects available. There are also opportunities to:

• apply your research in an industrial setting (DTP CASE studentships).

• undertake research jointly with our core and associate partners (Standard DTP studentships with an associate partner).

• work with other national/international researchers.

• undertake fieldwork.

Our structured training programme will ensure you are well equipped as a bioscience researcher, supporting careers into academia, industry and beyond. 

First year

We provide a broad awareness of the fundamental research approaches in life sciences and how they could be applied to real-life situations through:

• two rotation projects - both allied with but in different disciplinary areas related to the PhD project.
• three taught units - training in Statistics, Bioinformatics, coding, experimental design, innovation and understanding the impact of your research.

Of note: You will need to successfully complete the first year to progress into your second year of studies.  Also, if you are unable to continue your PhD, an MRes exit route is available upon successful completion of the first year.

Second to fourth years

The remaining years will be more like a conventional PhD, where you will focus on your PhD project.

Project Description

Membrane-bound compartments (organelles) in eukaryotic cells are no longer seen as isolated entities; they need to interact and cooperate in order to maintain healthy cellular function. Research on organelle cooperation represents an exciting new field in modern cell biology and biomedical sciences because of its close relation to organelle functionality and its impact on physiological processes. Peroxisomes are highly dynamic, oxidative organelles with essential functions in cellular lipid and redox metabolism. They closely cooperate with other subcellular organelles such as the endoplasmic reticulum (ER), mitochondria and lipid droplets, and fulfil important protective roles to combat cellular stresses (e.g. oxidative/lipid stress, immune defence) (Silva BBA 2020, 1867:118800). Peroxisome-organelle cooperation is mediated by membrane contacts. Previously, we revealed the molecular mechanism, function and regulation of peroxisome-ER contacts (Costello 2017, JCB 216:331; Kors 2022, JCB 221:e202003143), which have been linked to neurological disorders. Although our understanding of organelle contacts is increasing, we know very little about their physiological roles and their dynamics/dynamic alterations under cellular stress conditions. 

This multi-disciplinary project will therefore address fundamental questions related to the molecular and regulatory mechanisms that determine peroxisome-organelle interplay under normal and stress conditions. The student will use a variety of molecular cell biology, biochemical, as well as cutting-edge imaging techniques to develop cellular and in vivo models and tools to investigate organelle interplay under diverse stress conditions. Oxidative, lipid and protein stresses, including those associated with disease and ageing, will be generated by genetic and pharmacological manipulations. As peroxisomes have protective functions in the brain, studies will include neuronal cells, the use of ex vivo brain slices and fly models of dementia. Of particular interest is, if manipulation of peroxisome-organelle contacts can protect against stress-induced damage. The student will join a large molecular cell biology community and will generate knowledge that will advance our understanding of how organelle communication networks are modulated at the molecular, cellular and physiological level. Ultimately, this will reveal new strategies to combat cellular stress and promote healthy ageing.

Entry requirements

Academic criteria

Applicants for a studentship must have obtained, or be about to obtain, a First or Upper Second Class UK Honours degree, or the equivalent qualifications gained outside the UK, in an appropriate area of science or technology. Applicants with a Lower Second Class degree will be considered if they also have a Master’s degree or have significant relevant research or non-academic experience.

In addition, due to the strong mathematical component of the taught course in the first year and the quantitative emphasis in our projects, quantitative/mathematical experience is needed.  This can be demonstrated through one or more of the following:

• Undertaking units as part of your degree that have a significant quantitative/mathematical component*
• Maths or Physics A-level (grade B and above)

*Significant mathematical component examples include; maths, statistics, bioinformatics.

Applicants must ensure they highlight their quantitative/mathematical background within their application and to upload any supporting evidence.

To support accessibility to PhD training opportunities, these studentships are only available to applicants that have not previously obtained or about to obtain a PhD degree (or equivalent).

Language requirements

If your first language is not English, you will need to meet the minimum English requirements for the programme.  Further information about these English requirements >>

We ask that the language requirements are met by 1st June at the latest, to allow adequate time to obtain any necessary documentation to allow you to study in the UK.  Further information about documentation required >>

How to apply

Apply now

Please be aware you will be asked to upload the following documents:

• CV
• Letter of application outlining your academic interests, prior research experience and reasons for wishing to undertake the project.  Please indicate your preferred project choice if applying for multiple BBSRC SWBio DTP projects.
• Personal Statement
• Transcript(s) giving full details of subjects studied and grades/marks obtained.  This should be an interim transcript if you are still studying.
• Two academic referees - see information below about references.
• If you are not a national of a majority English-speaking country you will need to submit evidence of your proficiency in English (see entry requirements above)

The closing date for applications is midnight on Monday, 11 December 2024. 

Interviews will be held between 3-14 February 2025.

Reference Information

You will be asked to submit two references as part of the application process.  If you are not able to upload  your reference documents with your application please ensure you provide details of your referees.  If you provide contact details of referees only, we will not expect receipt of references until after the shortlisting stage. Your referees should not be from the prospective supervisory team.

If you are shortlisted for interview, please ensure that your two academic referees email their references to pgrapplicants@exeter.ac.uk, 7 days prior to the interview dates.  Please note that we will not be contacting referees to request references, you must arrange for them to be submitted to us by the deadline.

References should be submitted by your referees to us directly in the form of a letter. Referees must email their references to us from their institutional email accounts. We cannot accept references from personal/private email accounts, unless it is a scanned document on institutional headed paper and signed by the referee.

If you have any general enquiries about the application process please email pgrapplicants@exeter.ac.uk.

Project-specific queries should be directed to the primary supervisor.

Selection Process:

Information relating to the selection process can be found via the following link https://www.swbio.ac.uk/programme/selection-process/
Please note that nomination by a project supervisor therefore does not guarantee the award of a studentship.

Data Protection

During the application process, the University may need to make certain disclosures of your personal data to third parties to be able to administer your application, carry out interviews and select candidates.  These are not limited to, but may include disclosures to:
