ÐßÐßÊÓƵ

Dr Raymond Allan is a Senior Lecturer in Microbiology in the School of Pharmacy at ÐßÐßÊÓƵ. His research focusses on the investigation of bacterial biofilms, developing an understanding of the adaptive mechanisms they employ to enable their survival within the human host, and investigating their role in chronic infectious disease. His research also includes the identification of targets for the development and investigation of novel treatment strategies for biofilm-associated infections.

He has over 10 years’ experience investigating biofilm-associated infections at University of Southampton, the National Biofilms Innovation Centre, and Southampton NIHR Wellcome Trust Clinical Research Facility, joining ÐßÐßÊÓƵ in 2019.
