Joshua is a senior lecturer in biochemistry and molecular genetics in the College of Engineering and Science. After completing an undergraduate degree in applied biology, he completed a PhD in molecular biology and genetics at Victoria University and CSIRO (Plant Industry), characterising genes underpinning important quality characteristics in wheat.
He is currently a member of the Applied Ecology Research Group undertaking research into the molecular basis of invasiveness in weeds and the Advanced Food Systems Research Group undertaking research on food authenticity in a number of products, including olive oil and calamari.
Joshua is the course coordinator of the Bachelor of Science (Specialisations in Biotechnology, Chemistry or Environmental Management) and teaches biochemistry, molecular genetics and genetic engineering at the undergraduate level.
