PhD Studentship: The biology and ecology of disease in seagrass—Understanding the pseudo-fungus Phytophthora gemini and its impact on common eelgrass (Zostera marina) development University of Plymouth in United Kingdom

[Fully-funded ARIES studentship for 3.5 years, including tuition fees, maintenance stipend (£20,780 per annum for 2025/26, 2026/27 rate TBC), and research costs.] This PhD studentship at the University of Plymouth, in partnership with the Marine Biological Association and the Ocean Conservation Trust, investigates the biology and ecology of disease in seagrass, focusing on the pseudo-fungus Phytophthora gemini and its impact on common eelgrass (Zostera marina) development. Seagrass meadows are vital marine ecosystems that support biodiversity, stabilize sediments, and sequester carbon, but are increasingly threatened by climate change, pollution, and disease. Recent research highlights the role of microbial pathogens, particularly Phytophthora gemini, in undermining restoration efforts by infecting eelgrass seeds and seedlings. The project aims to fill a critical knowledge gap in understanding seagrass pathogens and their effects on restoration success, providing insights into disease mitigation strategies. The successful candidate will use laboratory assays, microscopy, and molecular techniques such as qPCR and metabarcoding to characterize pathogen life cycles, host responses, and environmental tolerances. Fieldwork at selected coastal sites will assess natural infection dynamics and collect samples for analysis. Restoration trials will be designed to test seed treatments and planting strategies under controlled and semi-natural conditions. The student will be based at the Marine Biological Association in Plymouth, with additional work at the University of Plymouth and the Ocean Conservation Trust, and will have opportunities to collaborate with UK and international research networks. Training will be interdisciplinary, covering microbiology, marine ecology, plant pathology, molecular biology, and restoration science, with a strong emphasis on applied ecological research. The student will develop skills in experimental design, statistical analysis, and scientific communication, and will have opportunities to attend international conferences, publish in peer-reviewed journals, and engage with stakeholders involved in seagrass restoration. The MBA provides a vibrant research environment with access to cutting-edge facilities and experienced mentors. Applicants should have a first or upper second class honours degree or a relevant Masters qualification in biology, marine biology, microbiology, environmental science, marine science, or a related discipline. Prior experience in microbiology, molecular techniques, microscopy, or fieldwork is advantageous but not essential. English language proficiency is required (IELTS Academic score of 6.5 with no less than 5.5 in each component test area or equivalent). The studentship is fully funded for 3.5 years, including tuition fees, a maintenance stipend (£20,780 per annum for 2025/26, 2026/27 rate TBC), and research costs. The application deadline is 7 January 2026. For informal enquiries, contact Professor Michael Cunliffe at [email protected].
