Peter received his PhD from the University of Western Australia in 2009, where he investigated exercise-induced mechanisms relevant to iron deficiency in endurance athletes. This work highlighted the potential influence of the iron-regulatory hormone, hepcidin, on iron metabolism. Peter has since worked as an applied sports physiologist within the Australian National Sports Institute Network, and he currently holds the role of Research Director at the Western Australian institute of Sport. Peter is also an Associate Professor in the School of Human Sciences at the University of Western Australia, where he teaches and researches in applied physiology, with a focus on sports nutrition and the iron requirements of athletes.
