Epidemiology, genomics and antimicrobial resistance of bacteria


I am a PostDoctoral Research Scientist at the Institute. My research interests include how pathogenic bacteria evolve, how they are transmitted and how they develop resistance to antibiotics. I completed my PhD at Massey University in 2017, studying the evolution and transmission of bacterial enteritis agents over the course of outbreaks.

In my current role, I use whole-genome sequencing to investigate the sources and spread of pathogenic and commensal bacteria, and the reservoirs and transfer of antimicrobial resistance in the food chain.
