My main research interest is plant immunity, with a focus on using structural biology and protein biochemistry to understand how plant pathogens cause disease, and those that plants employ to recognise pathogens and activate defence responses. I completed my undergraduate degree and subsequent PhD at Flinders University. During my PhD, I developed protein expression and protein biochemistry approaches to characterise the activation mechanisms of plant disease resistance proteins that belong to the nucleotide-binding oligomerization domain (NOD)-like receptors (NLRs) protein family. In 2009, I moved to the University of Queensland to work with Professor Bostjan Kobe utilising structural biology approaches to NLR protein function. In 2016 I moved to ANU, funded by an ARC DECRA Fellowship, to work with Assoc. Prof. Peter Solomon (http://biology.anu.edu.au/people/peter-solomon) in the wheat biosecurity laboratory (http://www.wheatbiosecurity.com). In 2018, I became a lab leader in the division of Plant Sciences - RSB. My labs focus is Plant Structural Immunology.
