Current studentships

Extremophilic polysaccharides for vaccine adjuvant engineering and immunogenicity (ExPoVA) (BBSRC Yorkshire Bioscience Doctoral Training Partnership)

Deadline: 07/01/2026 5:00PM
Studentship code: PHD
Staff name: Dr Sreejith Raveendran
Research centre: National Horizons Centre (Biosciences)
Start date: Successful applicants will be expected to start in October 2026.

The development of effective cancer vaccines is limited by the scarcity of safe adjuvants capable of driving strong, durable immune responses. ExPoVA is an interdisciplinary BBSRC-aligned project aiming to develop Mauran, a sulphated polysaccharide from the extremophilic bacterium Halomonas maura, as a promising yet unstudied tumour vaccine adjuvant. Mauran shows unique structural resilience and bioactive effects, yet its structure-activity relationship (SAR) and immunomodulatory potential remain largely unexplored, representing a key knowledge gap in biomanufacturing and biologics innovation. You will define these mechanisms and evaluate Mauran’s potential as a next-generation cancer vaccine adjuvant.

You will receive interdisciplinary training across structural biology, glycoscience, biophysics, microbial biotechnology, immunology and translational cancer research. Work will take place across Teesside University’s National Horizons Centre (NHC), BIOS laboratories and the glycoscience facilities at the University of Leeds, providing access to state-of-the-art analytical and biophysical platforms.

Project Aims
The project will define the structural motifs of Mauran that govern its immune activity. You will characterise its chemical architecture, determine how sulphation and branching patterns interact with innate immune receptors, and assess effects on dendritic-cell activation, cytokine release and T-cell priming. Comparing natural and engineered Mauran variants with standard adjuvants will identify the strongest candidates for tumour vaccine formulations.

You will study:
Innovation: Discover a new class of extremophilic polysaccharide adjuvants with applications in cancer immunotherapy.

Cutting-edge research methods: You will employ advanced tools such as NMR, XRD, FTIR, HPLC, mass spectrometry, glycan microarrays, SPR and molecular docking to map Mauran’s structural and receptor-binding features.

High impact cancer immunology: Using invitro immune models, you will assess dendritic-cell maturation, cytokine release, T-cell priming and anticancer benefits, comparing Mauran with benchmark adjuvants like alum and CpG.

Funding eligibility

This fully funded PhD Studentship covers tuition fees for the period of a full-time PhD Registration of up to four years and provide an annual tax-free stipend of £21,380 for three years, subject to satisfactory progress.

You must complete your PhD in four years. .

Applications are welcome from UK and international students.

Entry requirements

Applicants should hold or expect to obtain a good honours degree (2:1 or above) in a relevant discipline. A master's level qualification in a relevant discipline is desirable, but not essential, as well as a demonstrable understanding of the research area.

Applicants should have a background in biochemistry, molecular biology, polysaccharide chemistry, cancer immunology, structural biology or biophysics. Experience or strong interest in NMR, crystallography, glycan analysis or immunological assays is desirable. Enthusiasm for interdisciplinary research is essential.

International students should check if they meet the entry requirements for the host university.

We aim to support the most outstanding applicants from outside the UK and are able to offer a very limited number of bursaries that will enable full studentships to be awarded to international (EU and non-EU) applicants. These full studentships will only be awarded to exceptional quality candidates, due to the highly competitive nature of this scheme.

International students will be subject to the standard entry criteria relating to English language ability, ATAS clearance and, when relevant, UK visa requirements and procedures.

The YBDTP is committed to recruiting extraordinary future scientists regardless of age, ethnicity, gender, gender identity, disability, sexual orientation or career pathway to date. We understand that commitment and excellence can be shown in many ways and have built our recruitment process to reflect this. We welcome applicants from all backgrounds, particularly those underrepresented in science, who have curiosity, creativity and a drive to learn new skills.

Not all projects will be funded; a limited number of candidates will be appointed via a competitive process.

How to apply

To submit your application, complete the Expression of Interest form for any of the projects which interest you. You can apply for up to two YBDTP projects (which can be at different universities).

About Teesside

We are committed to providing a safe, welcoming and inclusive campus and to supporting all members of our University community to thrive whatever their age, gender, disability, sexual orientation, gender identity, race, marital status, nationality or any other characteristic.
More about our Inclusive campus

As a Teesside University research student, you will join a growing and dynamic research community, allowing you to share your experiences, insight and inspiration with fellow researchers. You will benefit from our academic expertise and be supported through a strong programme of research training. You will be offered opportunities and support at each stage of your research degree. Our research is designed to have impact, and to influence policy and practice within our region, the UK and beyond. We work with external organisations to anticipate and respond to research needs, and to put our research into practice in sectors as diverse as the arts, engineering, healthcare and computing.

PhD students are encouraged to work with their supervisors to explore the potential impact of their work.

The successful candidate will be expected to participate fully in research group and centre activities, including training sessions and workshops, and will become a member of the University's wider postgraduate research community. Mentoring and support will be provided for the development of a strong academic and professional CV during the PhD.

The YBDTP brings together world-class bioscience research and innovation, as well as excellence in doctoral supervision, across the Yorkshire and Teesside region. The YBDTP will fund postgraduate researchers at the Universities of Leeds, Sheffield, York, Bradford, Huddersfield, Hull, Leeds Beckett, Sheffield Hallam and Teesside forming a strong regional training partnership. In YBDTP you'll benefit from a regional doctoral training programme that has interdisciplinary collaboration at its core. The aim is to enable you to develop a range of research skills in biological, biotechnology and biochemical areas as well as equip you with core data analysis and professional skills that are necessary for bioscience research and related non-academic careers.
