The University of Plymouth invites applications for three 3.5-year PhD studentships within the Marine Institute, focusing on the development and evaluation of design criteria to end microplastic pollution. This project is part of a suite of eight research topics, with three studentships to be allocated based on candidate-project fit. The studentships are scheduled to begin on 1st October 2026.

Plymouth is renowned for its global marine research, hosting the largest concentration of marine researchers in the UK. The successful candidate will join the International Marine Litter Research Unit, led by Professor Richard Thompson, a world expert in microplastic pollution, and supported by Professors Kristian Syberg, Morten Birkved, and Kate Goldsworthy, who bring expertise in circular economy, performance assessment, and circular design.

The research will address the environmental impacts of microplastics, particularly those generated by the wear of tyres and textiles. The project aims to develop upstream solutions by creating comprehensive frameworks and criteria for safer and more sustainable product design. The work is highly relevant to the implementation of the UN global treaty to end plastic pollution and regional regulations such as Euro-7.

Methodologically, the project is predominantly desk-based, involving systematic reviews of microplastic shedding, sustainability, and chemical safety. The candidate will synthesize life cycle characteristics of materials, shedding behavior, toxicity, and end-of-life management for various design options. Supported by Life Cycle Assessment (LCA) and circular economy assessment, the research will evaluate the essentiality, safety, and sustainability of different product formulations for textiles and tyres, with broader applicability to sectors like agriculture and packaging.

Training will be provided in systematic review techniques, LCA, chemical hazard analysis, circular economy frameworks, and science-to-policy translation. The studentship offers a vibrant interdisciplinary environment and opportunities for secondments with global experts.

Eligibility requires a strong first degree in a relevant field (environmental science, LCA, product design, ecotoxicology, material science). A relevant postgraduate qualification or experience in textiles or transportation is advantageous. Non-native English speakers must meet the minimum IELTS Academic score of 6.5 (no less than 5.5 in each component).

Funding covers full Home or International tuition fees and a stipend at the UKRI rate (2026/27 rate to be confirmed; 2025/26 rate is £20,780 per annum). The final six months of the four-year registration period are self-funded. No additional funding is available for NHS Immigration Health Surcharge, visa costs, or flights.

To apply, submit an online application including CV, personal statement, degree certificates and transcripts, contact details for two referees, and proof of English language competency if required. The deadline for applications is 12 noon on Monday, 2nd February 2026. Shortlisted candidates will be notified after the deadline, with interviews expected in March.
