The University of Exeter Centre for Ecology and Conservation in Cornwall is offering a PhD opportunity focused on understanding how host microbiome dynamics affect wildlife disease. The project will use a One Health framework to investigate how microbiome changes in European badgers influence their susceptibility to bovine tuberculosis (bTB), and how these patterns are shaped by host social interactions and space use. This interdisciplinary research combines molecular and bioinformatic techniques, statistical modelling, and field sampling, providing a comprehensive training environment for the successful candidate. The project is supervised by Xav Harrison and Associate Professor Barbara Tschirrren, both based at the University of Exeter. The research will be conducted within a vibrant academic community at the Centre for Ecology and Conservation, with access to state-of-the-art facilities and field sites in Cornwall. The study is ideal for candidates interested in disease ecology, wildlife health, host-pathogen interactions, and the application of molecular and computational methods to ecological questions. Applicants should have a strong background in biology, ecology, or a related field, and experience with molecular and bioinformatic techniques, statistical modelling, and field sampling is desirable. The position is suitable for those with a good undergraduate or master's degree in a relevant discipline. The deadline for applications is December 3rd, 2025.
