Microbiology
Our multidisciplinary research group focuses on molecular microbiology, microbial ecology, genetics, evolutionary microbiology and the ways that these disciplines contribute to ‘One Health’ and the global issue of antimicrobial resistance (AMR).
The Microbiology research area is part of the wider Biomedical Research Group.
We offer a Biomedical Science PhD, and a range of innovative research project opportunities for postgraduate researchers.

Academic staff
Dr Caray Walker - Head of the Microbiology Research Group
Dr Caray Walker's research interests are in antimicrobial resistance (AMR) and pathogenesis of important bacterial pathogens, in particular, zoonoses. As part of this work Caray and her group are collaborating with The British Antarctic Survey to investigate the prevalence of AMR in Antarctica. She is also interested in the development of novel vaccines and diagnostic test candidates through exploitation of environmental factors which affect gene expression, such as iron.
Dr Helen McRobie
Dr Helen McRobie focuses her research interests around the pharmacological characterisation and pleiotropy of the MC1R gene. Her work on the genetic basis of melanism in grey, fox, red and palm squirrels was the basis of the Black Squirrel Project. Helen also has research interests in the sheltering effect in AMR of Klebsiella.
Dr Chris O'Kane
Dr Chris O'Kane conducts research into the development of novel therapeutics for AMR, and the application of nanotechnology in the development of theranostic devices.
Dr Clett Erridge
Dr Clett Erridge has a primary research interest in mechanisms connecting inflammation to lipid metabolism, particularly in the context of coronary artery disease and other inflammatory conditions associated with the liver. His interest also encompasses the impact that the gut microbiota can have on the immune system and in drug discovery technologies.
Dr Richard Jones
Dr Richard Jones's research interests include multidisciplinary studies of extracellular matrix and membrane proteins implicated in AMR and human eye, skin and vascular diseases. He has experience in molecular biology, protein expression and purification, and the analysis of proteins using biochemistry, biophysics and bioinformatic techniques. Most recently, Richard has collaborated with Dr Jim Sullivan in supervising a project on variants of oxa-beta-lactamases from Acinetobacter baumannii.
Dr Jim Sullivan
Dr Jim Sullivan pursues research interests in post translational modification of proteins in eukaryotic microbes along with investigating the mechanisms of antimicrobial and biocide resistance in bacteria. Areas of expertise include molecular cloning and the production and analysis of recombinant proteins.
Dr Bas Boots
Dr Bas Boots' academic interests are related to linking microbes, animals, plants and ecosystem functioning: from genes to ecosystems. Microbial communities associated with animals, including insects, bivalves and cattle. Development of technologies to detect pathogens and antimicrobial resistance in the environment. Impacts of anthropogenic pressures (e.g. pollutants) on ecological processes in aquatic and terrestrial habitats. Biogeochemistry, biodiversity and ecology of soil, water and sediment.
Post-doctoral research students
Dr Harisree Paramel Nair
Dr Harisree Paramel Nair has has research interests in microbial metagenomics, environmental microbes and zoonotic pathogens. Her current research focuses on the prevalence of enteric pathogens in wild birds and investigating the AMR mechanisms and virulence factors which contributes in making them highly pathogenic strains of health concern.
