Dr Jamie Whitfield is a recent PhD graduate with a research focus in the area of skeletal muscle metabolism and physiology. Jamie completed his BA (Honors Specialization) in Kinesiology at the University of Western Ontario, in London, Ontario (Canada) in 2011 where he gained an interest in whole-body exercise physiology. It was this interest that led him to return to his hometown of Guelph, Ontario (Canada) and pursue postgraduate training in the field of skeletal muscle metabolism at the University of Guelph. Jamie was awarded his PhD in June 2017 after defending his thesis entitled “Skeletal muscle mitochondrial and cytosolic metabolic responses to dietary and genetic manipulations”.

Jamie joined Australian Catholic University as a Postdoctoral Research Fellow in 2017. The goal of his work at the Mary MacKillop Institute for Health Research is to utilise a variety of research models to gain a better understanding of how dietary and exercise interventions can alter skeletal muscle metabolism; and can therefore be used to improve outcomes along the health spectrum – from pathology to performance.

Circadian rhythms are ~24-hour cycles common to almost all organisms and are essential for the regulation of biologic al processes underlying both whole-body and tissue-specific metabolism. Within the brain, a region known as the suprachiasmatic nuclei (SCN) reacts to light exposure via the optic nerve and acts as a “master” system-wide clock synchronizer to prepare cells for daily changes in environmental conditions. However, recent evidence has also raised the possibility of the existence of independent circadian clocks in peripheral tissues, including liver and skeletal muscle which are linked and coordinated by the SCN. Importantly, peripheral clocks are sensitive to diet-induced disruptions in circadian rhythm, resulting in increased susceptibility to a variety of pathologies, including metabolic syndrome, obesity, and type 2 diabetes. This suggests they play an important role in maintaining the alignment of internal physiological processes with external environmental cues. It is therefore important to understand the causal relationships between disturbances to circadian rhythm (i.e. those induced by nutrition and exercise) and functional health outcomes as this could uncover novel therapeutic strategies against metabolic disorders including insulin resistance and type 2 diabetes.
