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: 24 April 2026 About the MSCA project MICROSUNSET is a Marie Sklodowska-Curie Actions Doctoral Network (MSCA-DN) funded by the European Union. We are excited to announce 12 open positions for Doctoral Candidates (DCs). We aim to create a network of early-stage researchers equipped with the knowledge and skills - including entrepreneurship – needed to develop and support implementation strategies that addresses the prevalence of micronutrient deficiencies in Europe as diets shift toward more plant-based foods. For MICROSUNSET we will recruit 12 highly talented DCs where their collective research will focus on many different aspects to include investigations on bio-accessibility and bioavailability of micronutrients, and strategies to produce and process plant-based foods with enhanced concentration of micronutrients. Development of analytical methods, digestion models, dietary modelling, and conducting consumer surveys will form part of Doctoral Network’s tasks. The 12 PhD vacancies will be based across seven different universities in Europe: four in Denmark (three at the Technical University of Denmark and one at the University of Copenhagen), two in Germany (Technical University of Munich), one in the Netherlands (Wageningen University), one in Ireland (University College Cork), two in the United Kingdom (University of Newcastle upon Tyne), and two in Finland (University of Helsinki). To train the DCs as the next generation of micronutrient researchers in our international and interdisciplinary program, MICROSUNSET brings together experts from several disciplines as supervisors, forming a consortium of seven beneficiaries (see above) and fourteen associated partners including six from industry and two start-ups. For more information, please have a look at https://microsunset.dtu.dk/. To be eligible for a MICROSUNSET PhD-position, you must not have lived, studied, or worked in the host country for more than 12 months in the last 36 months, and must not already hold a doctoral degree. About the PhD-position (DC2) Are you interested in becoming part of MICROSUNSET and building a strong foundation for a successful research career? The Population Health Science Institute at Newcastle University is seeking highly motivated applicants for a PhD scholarship focused on determining of the bio-accessibility and bioconversion of provitamin A carotenoids from plant-based foods. You will join the multidisciplinary Human Nutrition and Exercise Research Centre with research spanning many different fields of nutritional and exercise sciences. If you're ready to push the boundaries in unravelling the key contributors to bio-accessibility and bioconversion of provitamin A carotenoids in plant-based foods, we invite you to apply and join the dynamic research teams involved in MICROSUNSET. Research objective The primary objective of this PhD project is to elucidate the factors governing the bioaccessibility and bioconversion of β‑cryptoxanthin and β‑carotene from a diverse range of plant‑based food sources, and to integrate these findings into future dietary intake assessments. This research will begin with the optimisation of an established in vitro digestion model to evaluate carotenoid bioaccessibility, followed by validation of key findings through a rigorously designed human intervention study. Advanced analytical mass spectrometry techniques, coupled with the use of stable isotope tracers, will be employed to quantify both the release of provitamin A carotenoids from food matrices and their subsequent metabolic conversion. A central component of the project will involve examining inter‑individual variation in bioaccessibility and bioconversion, comparing plant-based sources with oil-based β-carotene and β-cryptoxanthin supplements. This comparative approach will help to clarify how food matrix, formulation, and physiological variation contribute to differences in provitamin A utilisation among individuals. In addition to laboratory and human study components, the candidate will gain hands-on experience with evidence synthesis methodologies, including systematic reviews, and will analyse large-scale cohort datasets to examine patterns of carotenoid intake and status at the population level. This multi-layered approach will provide unique training across experimental, analytical, and population level research domains. Ultimately, this project is expected to generate significant new insights into the bioaccessibility and bioconversion of provitamin A carotenoids from commonly consumed plant foods. Furthermore, it will provide robust evidence regarding the reliability and translational value of in vitro models for predicting carotenoid bioaccessibility across diverse food matrices. The findings will have important implications for nutrition science, dietary recommendations, and food industry practices relating to the promotion of provitamin A rich foods. Throughout the project, you will collaborate with other Doctoral Candidates (DCs) in the MICROSUNSET consortium to contribute to generation of evidence-based knowledge about micronutrient intake, digestibility and bioavailability from plant-based diets. Part of the PhD-study will take place as external stay at Döhler GmbH, Darmstadt, Germany for three months and at the Technical University of Denmark (DTU) for two months. Responsibilities The primary goal of this PhD project is to investigate options for increasing vitamin A from plant-based foods in our food to support a healthier future European population. As part of your research, you will Enrol in Newcastle University’s doctoral school and comply with its doctoral training requirements Participate actively in the MICROSUNSET training, dissemination, communication and exploitation activities. Publish and present high-quality research results related to the research project in international conference proceedings and peer-reviewed scientific journals. Work actively to prepare and defend a doctoral thesis in the field of micronutrients and sustainable food products. Support student supervision and contribute to teaching at BSc and Master’s levels. Qualifications You must hold a two-year master's degree (120 ECTS points) in Nutrition/Biology or a similar degree at the equivalent academic level. Furthermore, the ideal candidate has: Completed a relevant master’s program Appropriate technical skills Experience with analytical equipment such as HPLC and LC-MS Experience conducting intervention studies with human participants Strong communication skills in English, both written and oral Strong collaboration skills and the ability to work effectively in interdisciplinary teams. A structured and analytical approach to work and problem-solving Willingness to attend all MICROSUNSET training events and own secondments Experience with research dissemination - publications or conference presentations - is preferred. Approval and Enrolment The scholarship for the PhD degree is subject to academic approval, and the candidate will be enrolled in the faculty of Medical Sciences Graduate School. For information about our enrolment requirements and the general planning of the PhD study programme, please see the Faculty of Medical Sciences postgraduate research page. Assessment The assessment of the candidates will be conducted by an assessment committee which follows the MICROSUNSET recruitment set-up and the Code of Conduct for the Recruitment of Researchers, (2005/251/EC) promoting an inclusive, merit-based, transparent, and unbiased recruitment process.
