Jean-Yves is a Professor Pharmaceutical Microbiology at Cardiff’s School of Pharmacy and Pharmaceutical Sciences. Jean-Yves research interest concerns antimicrobials and particularly biocides; their activity, mechanisms of action, the emergence of microbial resistance and cross-resistance to antimicrobials and the development of efficacy test protocols mimicking the real-world applications. Another research focus is dry surface biofilms – these are found on environmental dry surfaces and are widespread in healthcare settings where pathogens can be embedded. Jean-Yves’ team has developed protocols to form single and dual species dry surface biofilms to understand their formation but also their susceptibility to biocidal products and the impact if interventions on their transfer between surfaces. This is a new and interesting field of research which may have some significant impacts on healthcare associated infections.
