About this position
PhD opportunity at the University of St Andrews in the School of Biology / Biomedical Sciences Research Complex, as part of the EASTBIO BBSRC Doctoral Training Partnership.
The project is titled “Mechanism and consequences of lethal zygosis in bacteria restricting AMR plasmids” and focuses on antimicrobial resistance (AMR), conjugative plasmids, restriction-modification (RM) systems, bacterial defence systems, plasmid transmission, and phage therapy. The research asks how defence-induced lethal zygosis arises, how it varies across plasmids and defence systems, and what consequences it has for plasmid and phage infection dynamics.
Students will use experimental molecular and evolutionary microbiology, molecular biology, and bacterial genetics. Training may include mutant construction, flow cytometry, microscopy, and, depending on interest, bioinformatics, mathematical modelling, or experimental evolution. The student will join an interdisciplinary doctoral training environment and complete a 3-month placement in a non-academic setting.
Funding: competition-funded 4-year PhD with stipend at the UKRI standard rate and UK tuition fees covered. The advert states it is open to UK and international students, with the University of St Andrews covering the Home-International fee difference.
Eligibility / requirements: interest in microbiology, bacterial genetics, molecular biology, and evolutionary approaches; English language qualification if applicable; application materials include the EASTBIO application form, academic qualifications, and two references.
How to apply: complete the EASTBIO survey and application form, then submit an online application via the University of St Andrews portal for the course “PhD with internship.” Send the EASTBIO reference form to referees and ensure all required documents are uploaded.
Supervisor: Dr Tatiana Dimitriu (with Prof M F White also named on the advert). Informal enquiries: [email protected].
