Investigating the evolution of antimicrobial resistance

Listeria and other invasive pathogens

I am a postdoc working with Matt Gilmour and Mark Webber investigating the mechanism of action of novel antimicrobials and bacterial survival strategies against these antimicrobials. I recently completed my PhD with Mark Webber on the relationships between biofilm formation and efflux activity in Enterobacteriaceae using TraDIS-Xpress, a massively parallel transposon mutagenesis approach developed at the Quadram Institute. Previous to my PhD, I completed an MSc in Biomedical Sciences Research from the University of Bristol and a BSc in Evolutionary Biology.
