Research interests

Almost one third of Australians are directly affected by obesity- a complex chronic disease that is associated with an elevated risk of type-2 diabetes, heart disease, and several cancers. Obesity and its related complications can adversely impact quality of life and impose a substantial financial strain to individuals and healthcare systems. Research shows that losing 5% or more of baseline body weight can mitigate adverse effects of obesity on an individual’s health, including lowering the risk of developing type 2 diabetes. However, sustaining weight loss and its health benefits over the long-term, and improving access to effective strategies to manage obesity sustainably and equitably, are major challenges.


The main goal of our research group is to reduce the impact of obesity on health and wellbeing. Our research focuses on the neuroendocrine regulation of appetite and eating behaviours, the clinical application of obesity therapeutics and improving access to care. We are conducting several clinical studies to understand how best to integrate new treatments for obesity alongside established therapies to improve health outcomes, sustainability and access to care. Ultimately, these studies aim to address unmet clinical needs, enable the provision of high-quality, evidence-based healthcare, and reduce weight-related stigma.
