Infectious diseases affecting bees pose a serious threat to both biodiversity and food security. Many honeybee pathogens are shared by other wild bee species and crops are experiencing considerable yield gaps owing to insufficient pollination. Therefore, novel strategies that mitigate and prevent infectious agents to pollinators are urgently needed. Here we propose to monitor the microbiome of beehives to forecast the incidence and prevalence of honeybee pathogens. Our group has recently discovered that honey carries DNA of many different bacteria derived from bees, plants, soil, and water (Santorelli et al. 2021; https://doi.org/10.1101/2021.08.25.457643). Furthermore, we have observed that this bacterial diversity is dependent on the geographical location, suggesting a unique microbial feature for every hive that could be exploited as an indicator and predictor of bee pathogens.
We aim to monitor changes in the microbiome of the beehive using the DNA of honey samples. The DNA sequencing results will be complemented with additional data such as the impact of beekeeping methods and the main environmental bacteria present in the beehives, which, together, will inform of the levels of the gut bacteria in the bee colony and the presence or absence of microbial pathogens. The combination of environmental factors with significant microbial variations will enable us to generate algorithms illustrating the bee gut bacteria that associate with health or disease.
Training opportunities and student profile
The selected PhD student will benefit from training in molecular microbiology high throughput technologies such as 16S rRNA sequencing, and advanced computational analysis. Furthermore, the candidate will gain knowledge on beekeeping and farming practices through field sampling, surveys and meetings with beekeepers, farmers and ecologists. This project is therefore suitable for students with a degree in biological sciences, microbiology or a closely related science. The PhD student is expected to contribute intellectually to the development of the project to maximize the results obtained. This person will develop laboratory and scientific skills to become a well-trained molecular & computational microbiologist with expertise in bee ecology.

This is a collaborative project between The University of Surrey, The University of Sussex, Wisley Gardens, Royal Horticulture Society (RHS), The British Beekeepers Association (BBKA) and Queen’s University Belfast (QUB).
The principal supervisors are Dr Jorge Gutierrez-Merino, a veterinarian with an extensive track record in Applied Microbiology, particularly in the area of beneficial microbes, and currently working as a Senior Lecturer at Surrey University ([Email Address Removed]); and Dr Elizabeth Nicholls, a bee ecologist with expertise in leading landscape-scale field experiments investigating the impact of pathogens on whole honeybee hive health, and recently awarded a UKRI-Future Leaders Fellowship to study bee foraging decisions at Sussex University.
Open to UK students, with the project starting in October 2023.
You will need to meet the minimum entry requirements for our PhD programme https://www.surrey.ac.uk/postgraduate/biosciences-and-medicine-phd#entry.
Previous education in microbiology and environmental sciences is desirable; and ideally having some experience in genomics and bioinformatics. The person recruited for the PhD is also expected to have (or be willing to develop) beekeeping skills, therefore they will ensure that the beehives selected for the study are carefully managed, and that sample collection is appropriately conducted.
How to apply
Applicants are strongly encouraged to contact the relevant principal supervisor(s) to discuss the project(s) before submitting their application. Please contact Dr Jorge Gutierrez-Merino at [Email Address Removed]
Applications should be submitted via the https://www.surrey.ac.uk/postgraduate/biosciences-and-medicine-phd programme page (N.B. Please select the October 2023 start date when applying).
You may opt to apply for a single project or for 2 of these Pathogens and Host Defences Doctoral Training Partnership studentship projects
When completing your application, in place of a research proposal, please provide a brief motivational document (1 page maximum) which specifies:
- the reference numbers(s) for the project or two projects you are applying for,
- the project title(s) and principal supervisor name(s)
- if apply for two projects, please also indicate your order of preference for the projects
