School of Medical Sciences - Exercise Physiology ProgramStatement of Interests:
Type 2 diabetes (T2DM) remains a complex and multifaceted disease, the exact causes of which have yet to be resolved. While genetic predisposition can contribute to the development of T2DM, diet and physical activity can also have a positive impact on insulin sensitivity. Epigenetic modifications provide a mechanism by which external environmental factors such as exercise and diet can modify genetic predisposition for health and disease. My research activity is focused on the mechanisms underlying metabolic disorders with particular attention on human skeletal muscle. We identified that changes in the metabolic environment could lead to a dynamic epigenetic modulation of genes that have been implicated in the control of insulin sensitivity and the development of T2DM and related metabolic disorders.

The effects of maternal nutrition interventions on appetite, body weight, hormones (plasma leptin, insulin), lipids, and brain peptide expression invovled in appetite and glucose metabolism in offspring are of interest. A palatable high fat diet (32% fat) is being used to induce maternal obesity. This approach will be used to address the possibility of preventing childhood obesity by drugs and behaviour interventions. A second area of study deals with the effects of cigarette smoking on appetite, body weight, plasma leptin, and hypothalamic peptides expression to address wasting diseases.

School of Medical Sciences - Department of PharmacologyStatement of Interests:
Obesity - Alterations to brain Neuropeptide Y (NPY) causes increase food intake. Our laboratory is exploring the brain mechanisms involved in appetite. Obesity is a world-wide problem. The brain regulates appetite throught the actions of a complex array of neurotransmitters that either increase or decrease feeding. Professor Morris and her team use animal models of obesity to explore the brain mechanisms involved in appetite, and the changes that occur in these systems during the development of obesity. Their work aims to improve our understanding of how the brain regulates feeding and to provide new insight into potential treatments for obesity and other feeding disorders. Diabetes - The effect of diabetes on how the brain senses hypoglycemia Epilesy - Collaboration with Royal Melbourne Hospital, examining the involvement of NPY on absence seizures. Further work examines the mechanisms by which some anti-epilepy drugs make seizures worse.

In the field of neuroscience, I examine the effects of palatable feeding on the development of obesity and any subsequent changes on the brain and behaviour.

School of Medical Sciences - Exercise Physiology ProgramStatement of Interests:
There is an obesity epidemic in Australia which leads to metabolic dysfunction. The ways in which exercise and physical activity can ameliorate these problems are being explored. Collaborative work with St. Vincent's Hospital and Garvan Institute is concerned with changes in insulin and body composition during high intensity intermittent exercise.
