GM studied BSc Biological Sciences at the University of Leicester after which she remained in Leicester to do her PhD with Professors Tim Mitchell and Peter Andrew where she worked on Streptococcus pneumoniae. After her PhD GM worked at the Veterinary Laboratories Agency (VLA) where she spent 9 years as a senior research scientist managing a team of scientists carrying out research into the pathogenesis of Campylobacter jejuni. The research at the VLA, which was funded primarily by DEFRA and the Food Standards Agency (FSA), was focussed on distinguishing pathogenic from non-pathogenic strains of C. jejuni to identify markers of pathogenicity and to investigate control strategies to remove this major human pathogen from the food chain. Following that GM moved to Nottingham Trent University (NTU) as a Senior Lecturer in Microbiology. Throughout the twelve and a half years at NTU GM taught Microbiology to students at all levels on Biology, Biomedical Science and Forensic Science courses, whilst remaining research active. Promotion to Principal Lecturer saw GM take on the role of Post-Graduate Courses Manager as well as Outreach coordinator for the team. GM was then appointed Acting Head of Bioscience in August 2014, the role in which she continued until moving to University of Wolverhampton in September, 2017.
Food-borne pathogens: Campylobacter jejuni, C. coli.
GM’s research is focussed on the major human food-borne pathogens Campylobacter jejuni and C. coli and in particular on the molecular basis of pathogenesis of this organism as well as understanding how the organism has evolved to become such a pathogen and occupy a range of different niches. More recent research has been in the use of probiotics as a way of reducing Campylobacter in the food-chain.
