About the Project

The BBSRC-funded South West Biosciences Doctoral Training Partnership (SWBio DTP) involves a partnership of world-renown universities, research institutes and industry across the South West and Wales.

This partnership represents a distinctive group of bioscientists, with established international, national and regional networks, and widely recognised research excellence.

We aim to provide students with outstanding interdisciplinary research training within the following themes, underpinned by transformative technologies:

These are growth areas of the biosciences and for which there will be considerable future demand.

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). 

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   

  associatepartner).

• 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. 

Project Description

Evidence is accumulating that a father’s condition can be transferred non-genetically to the next generation and affect offspring development, performance and health. To date, the mechanisms underlying such paternal condition transfer effects remain poorly understood and their evolutionary consequences are largely unexplored.

In this project you will use a bird model system (Japanese quail, Coturnix japonica), in which paternal condition-transfer effects on offspring reproductive performance have previously been demonstrated, to identify the origin, function and evolutionary consequences of non-genetic paternal effects using a highly multidisciplinary and integrative approach. Using in vivo experiments, combined with state-of-the-art - omics and physiological techniques, you will test how favourable or harsh early life conditions experienced by males affect their sperm and seminal fluid composition, and how different components of the male’s ejaculate mediate cross-generational effects on the daughters’ reproductive performance and health.

Experimental in vivo and molecular work will be complemented by evolutionary modelling to quantify the role of paternal condition-transfer effects in altering the response to selection, as well as the potential of experimental interventions to modify evolutionary trajectories of reproductive traits under selection through paternal effects. The project will provide fundamental novel insights into the mechanisms underlying paternal condition-transfer effects across generations and the potential of early life interventions to alter evolutionary trajectories, both directly relevant to the management of animal health and performance as well as our understanding of the reproductive lives of birds.

During the project you will obtain interdisciplinary training in a variety of state-of-the-art approaches and techniques that are highly sought-after by employers in and outside of academia, including experimental in vivo skills, molecular techniques, bioinformatics, and mathematical modelling. You will be based in a thriving, friendly and inclusive department and benefit from the complementary expertise of a highly multidisciplinary supervisory team.

Part Time and Flexible Study Options

Part time study options maybe available please discuss with the supervisor. For further information please see - https://www.swbio.ac.uk/project-adjustments-part-time-study-and-flexible-working/

Due to complexities and restrictions associated with visas for part-time studies, we are currently unable to accept part-time international students to the programme.

Entry Requirements

Applicants should 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 Masters degree or have significant relevant 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).

How to apply

The closing date for applications is midnight on Monday, 5 December 2022. Interviews will be held between 1st and 15th February 2023.

If you have any general enquiries about the application process please email [Email Address Removed].

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

For further information and to submit an application please visit - https://www.exeter.ac.uk/study/funding/award/?id=4563

Selection Process:

Please note, the studentship selection process will take place in two stages:

1.    The project supervisors will consider your application and may invite you to visit for an informal interview. You can apply for more than one BBSRC SWBio DTP project, although supervisors may take into account your interest and commitment to their particular project. If you apply for multiple projects, please indicate your preferred project choice in your letter of application. Each application for an individual project will be considered separately by the project supervisors.

2.    After closure of applications, each supervisory team will then nominate their preferred applicant. A shortlist will be selected from these nominations and shortlisted applicants will be invited for interview on a selection day at the University of Bristol.  Please note that nomination by a project supervisor therefore does not guarantee the award of a studentship.
