Accepting PhD Students

PhD projects

Applications for early-career fellowships or to study a PhD in Microbiology are welcomed. Areas of study could be in Medical Microbiology, investigating how pathogenic bacteria survive and proliferate in the human body, or in Environmental Microbiology, deciphering how bacteria contribute to cycling of sulphur and nitrogen in the environment. Applicants are warmly encouraged to get in touch for informal discussions, see below for additional details.

Personal profile

Postgraduate Research Opportunities

Applicants with a background in Microbiology, Molecular Biology, Biomedical Science or Biochemistry are currently being sought for a fully-funded PhD scholarship available for commencement in October 2024. Interested candidates should apply directly by emailing with the subject '2024-PhD candidate'

NB: Due to funding requirements, this opportunity is only open to UK applicants eligible for home tuition fees status.  

Key Research Interests

Research Interests:

  • Understanding novel mechanisms of virulence and pathogenesis in Group B Streptococcus

  • Defining new ways that bacteria can make or break the important osmolyte dimethylsulphoniopropionate (DMSP)

  • Investigating molecular mechanisms of bacterial prodution of nitrous oxide (N2O), a potent global-warming gas


Matt is a Lecturer in the School of Biological Sciences with interests in Medical and Environmental Microbiology. Matt's research studies how pathogenic bacteria sense and respond to changes in their environment (ie. the human body) and how they exploit diverse niches to grow and proliferate. Matt also has expertise in studying metabolic pathways for nitrogen and sulphur cycling in environmentally-relevant bacteria, and how these microbial processes contribute to regulation of our climate.
