My research group studies the molecular mechanisms of antibiotic resistance with focus on understanding how, where, when and why bacteria evolve antibiotic resistance.

I am particularly interested in bacterial biofilms and we are investigating how bacteria adapt to antimicrobial pressure within a biofilm.

My group uses a variety of contemporary molecular microbiology approaches to study bacterial survival and resistance mechanisms in conditions relevant to the food chain.

Before joining the Quadram Institute I led a research group at the University of Birmingham, which I established during a BBSRC David Phillips fellowship studying the evolution of biocide-antibiotic cross resistance.

I have published over 60 articles relating to antimicrobials and have acted as an editor for the Journals of Antimicrobial Chemotherapy and Medical Microbiology as well as PLOS ONE.
