The Webber group investigates the genetic mechanisms of antimicrobial resistance with the aim of understanding when, where and how bacteria become resistant to antimicrobials. We are also interested in various aspects of biofilm biology and has projects investigating mechanisms to prevent biofilm formation, disrupting or killing of existing biofilms as well as studying spatial and temporal variation of viability and gene expression within biofilms.

We have expertise in various in vitro models of biofilm formation and experience working with Salmonella, E. coli, Pseudomonas, Acinetobacter, Staphylococci and other species. We also have expertise in in vitro evolution experiments, genomics and have developed assays to measure antimicrobial accumulation within cells. Expertise in the use of microscopy and flow cytometry analysis of recovered cells has been developed to study bacterial viability and to measure gene expression within individual cells in biofilms. Collaborations with modelling groups exist to help utilise data from biofilms and to create predictive models to understand bacterial behaviour and interactions within biofilms.
