<h2 class="heading hide-accessible">Summary</h2>

This PhD will improve our molecular understanding of hydrocolloids, the natural food polymers found in many everyday products that influence texture, stability and quality but whose fine molecular structure is not yet fully understood. Working closely with Nestlé Research in Lausanne, the project will use enzymes to selectively modify chemical linkages within hydrocolloids of interest, then characterise the resulting changes in viscoelastic and rheological behaviour, supramolecular structure and non-equilibrium states such as gels. The project will also explore the use of under-utilised waste and fibre-rich side-streams to produce high-value functional ingredients, supporting Nestlé's work on more sustainable food products.<br /> <br /> The project offers hands-on experience with a range of advanced soft matter characterisation techniques, including light- and x-ray scattering, bulk- and micro-rheology, fluorescence lifetime microscopy and Atomic Force Microscopy, alongside contributing to the development of new measurement methods such as passive particle tracking micro-rheology and differential dynamic microscopy. Based within the School of Physics and Astronomy and the School of Molecular and Cellular Biology at Leeds, the student will receive training across physics, food science and biochemistry, with a dedicated placement at Nestlé Research in Lausanne providing direct experience of a world-leading food R&D environment and a wider network of industrial contacts.

<p dir="ltr">The <a href="https://www.ifst.org/">Food Consortium IDLA</a> is committed to equality, diversity, and inclusion, welcoming applications from all backgrounds and fostering an environment where every researcher can thrive.</p> <p dir="ltr">The <a href="https://www.ifst.org/node/18889">studentship</a> is suited to candidates from physics, physical and bio-chemistry, food science or related disciplines, with an interest in soft matter physics, rheology, advanced microscopy or scattering techniques, carbohydrate chemistry, enzymology or analytical chemistry. Given the multidisciplinary nature of the project, candidates are not expected to have experience across all of these areas, and full training and support will be provided; curiosity, problem-solving ability and a willingness to work across disciplines matter most. The student will benefit fully from the collaboration with Nestlé, including a placement at Nestlé Research in Lausanne during the PhD, with flexible arrangements available to support inclusive working and studying throughout, and access to Nestlé's R&D facilities and relevant technologies.</p> <p dir="ltr">This studentship forms part of the Food Industrial Doctoral Landscape Award (IDLA), a training programme combining research-led innovation with real-world industry application, bringing together 8 leading UK food manufacturers and universities to address challenges facing the UK food and drink sector. Alongside doctoral research, students receive entrepreneurial training from the Haydn Green Institute, bespoke business training from global food industry players, and free access to the IFST platform MyCPD for career development. Participating in IDLA also means joining an interdisciplinary cohort of researchers working on food sector challenges affecting both people and planet.</p> <p dir="ltr"><strong>Other conditions</strong></p> <ul role="list"> <li aria-setsize="-1" data-aria-level="1" data-aria-posinset="1" data-font="Courier New" data-leveltext="o" data-list-defn-props="{"335552541":1,"335559685":720,"335559991":360,"469769226":"Courier New","469769242":[9675],"469777803":"left","469777804":"o","469777815":"multilevel"}" data-listid="24" role="listitem"> <p paraeid="{523ca1e8-0965-4138-a426-c8a6338b6f29}{36}" paraid="1376737542">Awards must be taken up by 1 February 2026 </p> </li> <li>The awards are available for new Postgraduate Researchers undertaking full-time research study leading to the degree of PhD.  </li> <li aria-setsize="-1" data-aria-level="1" data-aria-posinset="4" data-font="Courier New" data-leveltext="o" data-list-defn-props="{"335552541":1,"335559685":720,"335559991":360,"469769226":"Courier New","469769242":[9675],"469777803":"left","469777804":"o","469777815":"multilevel"}" data-listid="24" role="listitem"> <p paraeid="{523ca1e8-0965-4138-a426-c8a6338b6f29}{60}" paraid="1884643475">Applicants must live within a reasonable distance of the University of Leeds whilst in receipt of this Studentship/ scholarship. </p> </li> </ul>
