Jon's research interests centre on bacterial metal ion homeostasis and resistance, antimicrobial resistance, co-selection, and pathogenic enterobacteria. Current research areas include:
Bacterial resistance to antimicrobial metals.
Gene regulation of antimicrobial metal resistance genes.
Antimicrobial resistance plasmids and co-selection in Gram-negative bacteria.
Laboratory and pathogenic Escherichia coli.
Molecular methods for studying bacterial gene regulation and expression.
Molecular methods for engineering Gram-negative bacteria.
