My research interest focuses on microbial pathogenesis and antibiotic resistance; with specific interest in staphylococcal biofilm formation and its role in pathogenesis of biomaterial-related infections and nosocomial infections. I am a highly skilled researcher with excellent knowledge in Staphylococcus aureus and S. epidermidis adhesion and biofilm formation mechanisms. This involves studying the effect of relevant genes on the adhesion and biofilm formation of staphylococci to implant surfaces using various molecular biology techniques and whole genome sequencing. I am also competent in using confocal laser scanning microscopy, scanning electron microscopy, transmission electron microscope, and immunolabelling techniques.  I help supervise both undergraduate and postgraduate students working on a variety of staphylococci and Campylobacter pathogenicity projects in collaboration with the Abertawe Bro Morgannwg University Health Board (ABMU), Public Health Wales, and AO Research Institute Davos, Switzerland.

I am/have been a co-applicant on a Coleg Cymraeg Cenedlaethol PhD studentship, an MRC research grant and a InvestorG8 grant. I also manage the Microbiology and Infectious Diseases laboratory. I peer-review for several high impact journals and I am a member of the European Cells & Materials Journal’s International Editorial Review Board. I am a member of the Management Committee of COST Action TD1305, Improved Protection of Medical Devices Against Infection (IPROMEDAI). I am an active member of the Microbiology Society (formerly known as Society for General Microbiology), American Society of Microbiology, and the Society for Applied Microbiology.
