Research Assistant/ Associate in Bacteria-Host Interactions

Newcastle University; Newcastle upon Tyne; On-site; GBP 34,000 - 40,000; Full time

Job summary

Newcastle University is seeking a Research Assistant/Postdoctoral Research Associate to join the laboratory of Dr James Connolly in the Biosciences Institute to investigate sphingolipid synthesis in Gram-negative bacteria. This project is part of a Wellcome Trust Discovery Award.

The successful candidate will combine bacterial genetics, omics approaches and in vivo models to study how sphingolipid expression is regulated within the host and its effect on colonisation and microbiota interactions.

Qualifications

• PhD in microbiology or related discipline.
• Experience in bacterial genetics and omics data handling is preferred.
• Strong communication and collaboration within multidisciplinary teams.

Responsibilities

• Collect, analyse and interpret research data and draw conclusions on the outcomes.
• Coordinate own work with that of others, use problem solving to affect the achievement of research objectives and contribute to the planning of the project(s).
• Present information on research progress and outcomes to a Principal Investigator or groups overseeing the research project.
• Write up results from own research activity and provide input into the research project’s dissemination, in whatever form (report, papers, chapters, books).
• Use research resources (including, where required, laboratories, workshops and specialist equipment) as appropriate.

Research Assistant/ Associate in Bacteria-Host Interactions

Requisition ID: 29752

Location: Newcastle, GB

Contract Type: Fixed Term

Working Pattern: Full Time

Posted Date: 11 Sept 2026

Salary: Research Assistant £33,951 to £35,608 per annum

Research Associate £36,636 to £39,906.00 per annum

Newcastle University is a great place to work, with excellent benefits . We have a generous holiday package; plus the opportunity to buy more, great pension schemes and a number of health and wellbeing initiatives to support you.

Closing Date: 9 October 2026

The Role

We are seeking an ambitious Research Assistant/Postdoctoral Research Associate to join the laboratory of Dr James Connolly in the Biosciences Institute, to uncover the molecular details and impact of sphingolipid synthesis in Gram negative bacteria. This project is part of a collaborative Wellcome Trust Discovery Award.

For decades, sphingolipids were thought to be almost exclusively eukaryotic membrane components, with only a handful of unusual bacteria capable of producing them. Our recent discoveries have overturned this view, revealing that sphingolipid biosynthesis is widespread across diverse bacteria. Emerging evidence suggests sphingolipids are key determinants of membrane homeostasis, environmental adaptation, antimicrobial resistance and host-pathogen interactions.

Yet fundamental questions remain unanswered: How are diverse sphingolipids synthesised by bacteria and why do they provide a colonisation advantage to bacteria in the mammalian gut?

The successful candidate will drive this project by combining demonstrated expertise in bacterial genetics, ‘omics approaches and in vivo models. You will determine how sphingolipid expression is regulated within the host, and how these membrane components impact on colonisation dynamics as well as competition with the microbiota. Additionally, you will use multi-omics methods to profile the intestinal environment in response to sphingolipid expressing bacteria.

You should be highly motivated, organised and able to work independently. This project forms part of a wider collaboration between multiple groups, so the successful candidate should also be excellent communicator and capable of sustaining close, interdisciplinary collaboration.

This is a fixed-term appointment, available for 3 years in the first instance (with possibility to extend) and is available from autumn/winter 2026.

We follow the Researcher Development Concordat: Researcher Development | Our Research | Newcastle University . We enable all colleagues to fulfil their research potential regardless of career stage. This commitment secures our thrivingresearch culture and vibrant research environment. Our offer to each individual and their researcher development includes mentoring, annual research planning discussions, pooled research funding to support career development and research activities, peer review support for the development of research and innovation funding applications’.

As a Wellcome Trust funded role, the successful applicant may be eligible for the Endorsed Funder Route of the Global Talent Visa. We can provide an interest free loan scheme to support applicants who need to apply for a visa

We want you to feel confident when applying for a position with Newcastle University. If you would like an informal discussion to clarify any points, please contact James Connolly ([e-mail]).
