Bacterial gene regulation and evolution broadly sum up Josh’s main research interests. Since 2013, he’s led a research lab at CHIRI that studies mobile genetic elements active in both human pathogens and beneficial plant-associated microbes.

Josh’s current focus is on an opportunistic human and animal pathogen called Staphylococcus aureus and how, through a process of horizontal gene transfer, the bacteria evolve antimicrobial resistance. This resistance can reduce treatment options for infections, which is particularly problematic in hospital and community settings, where outbreaks may result in symptoms ranging from soft tissue abscesses to life-threatening sepsis and pneumonia.

Josh’s studies of antimicrobial resistance are relevant to a range of age-associated diseases studied at CHIRI as bacterial infections become increasingly common as we age.

Since 2017, Josh has secured more than $2.9 million in grants and fellowships towards his research. His current research is funded by an Australian Research Council (ARC) Future Fellowship ($780,000) and a National Health and Medical Research Council project grant ($735,585).

A little more about Josh’s career – after completing his PhD at New Zealand’s University of Otago in 2008, he spent four years as a University of Cambridge Herchel Smith Postdoctoral Fellow in the UK. He then returned to Otago Uni as a Health Sciences Career Development Fellow before coming to CHIRI.

Research interests – bacterial gene regulation; antimicrobial resistance.
