ENRG: Eating disorders and Nutrition Research Group

About

The Eating disorders and Nutrition Research Group (ENRG) aims to advance nutrition and dietetic research in eating disorders, improving our understanding of the role of nutrition in prevention and treatment. Located within ‘Eating Disorders and Body Image’ at Western Sydney University, ENRG is a collaboration of researchers with a record of accomplishment in nutrition-related research across the eating disorder continuum of care - from prevention and early intervention, to medical stabilisation and nutritional rehabilitation, to the normalising of eating patterns and behaviours. By supporting nutrition-focused research and advocating for the contribution of dietitians in the eating disorders field, the Group endeavours to enhance the understanding of the role of nutrition in eating disorder development and management, support evidence-based care and improve outcomes for people with eating disorders through increased access to high quality nutrition interventions.

Members of ENRG are committed to supporting dietitians and researchers with an interest in nutrition-focused research to undertake higher degree research in eating disorders.

Directors

Gabriella Heruc (opens in a new window)

Adjunct Associate Professor, School of Medicine

Primary Interests: The role of the dietitian in eating disorder management across the age and diagnosis spectrum; blood glucose regulation in eating disorders; gastrointestinal function and appetite changes in eating disorders; the physiological effects of starvation and changes with refeeding.

Susan Hart

Conjoint Associate Professor, School of Medicine

Susan has worked 25 years as a clinician, researcher, and leader in nutrition management of eating disorders. She is currently the Eating Disorder Coordinator at St Vincent’s Health Network and has skills in program management and service development having worked across in inpatient and outpatient settings, in both private and public health. She has contributed to the expansion of the evidence base for dietetics by conducting research that have primarily been on nutrition and dietetic practice in eating disorders. Highlights of my work include the REAL Food Guide, published in 2018 which is an education and clinical tool widely used in Australia and internationally. Her current research grants are investigating barriers and facilitators to screening, diagnosis and management of eating disorders in the emergency department and general acute care settings. She also investigating comorbid eating disorders in people with type 1 diabetes.

Melissa Hart

Conjoint Senior Lecturer, School of Medicine

Primary interests: Eating behaviour and nutrition in people with an eating disorder as well as the role of dietitians in the prevention and treatment of disordered eating.

Kylie Matthews-Rensch

Adjunct Fellow, School of Medicine

Primary interests: Dr Kylie Matthews-Rensch is a clinical and research dietitian at the Royal Brisbane and Women’s Hospital who obtained her PhD in 2019. Kylie’s research focuses on the translation of research into clinical practice, particularly in the fields of refeeding syndrome and for patients with eating disorders. Her research in both fields has received national recognition and has impacted clinical practice guidelines across Australia.  Kylie's current interests in eating disorder research include: refeeding syndrome, acute hospital management, hospital discharge support, and staff, patient and carer experience through treatment.
