Biographical details

Dr Elizabeth Cayanan is an accredited Exercise Physiologist and Nutritionist and is also a clinical research fellow in the Sleep and Circadian Research group at the Woolcock Institute of Medical Research, supported by the NHMRC Centre of Research Excellence, NeuroSLEEP. Her clinical research fellowship focuses on implementing clinical nutritional and exercise physiology pathways for patients with sleep and circadian disorders. Elizabeth was awarded a rapid translational grant from the Medical Research Future Fund to test the implementation of a comprehensive weight loss lifestyle programme she developed in patients with obstructive sleep apnoea at Royal Prince Alfred Hosptial. In addition, she is in a collaborative international research group partnered with National Taiwan University to investigate the food intake and preferences in shift working nurses.

Elizabeth graduated with first class honours in exercise, sports science and nutrition from the University of Sydney where her research focused on the cardio-metabolic effects of high intensity interval training compared to traditional weight loss exercise. She received a prestigious postgraduate award scholarship, and completed her PhD in the field of obstructive sleep apnea and obesity management at the Woolcock Institute of Medical Research, the University of Sydney. She has led weight loss intervention programmes for overweight and obese patients with obstructive sleep apnoea, PCOS, diabetes and other chronic conditions in both clinical and research settings and has extensive experience working in multidisciplinary teams.

Dr Cayanan commenced her role at Sydney Nursing School as a Scholarly Teaching Fellow immediately after her PhD was awarded and is passionate about education. She maintains a clinical workload in public and private settings, consulting patients with a range of chronic diseases to aid lifestyle management and long-term weight loss maintenance. Her clinical expertise, strong background in physiology and overlap with nurses in multi-disciplinary settings positioned her well in Sydney Nursing School. She endeavors to deliver a high-quality and scientific understanding of complex health diseases and disorders and draws significantly from her extensive clinical experience to provide an integrated insight into interdisciplinary care. Dr Cayanan contributes constructive input regarding the learning and teaching environment and processes to enhance the quality of teaching to enhance student experience.

Dr Cayanan is also a part of a grant awarded to re-invigorate the website for first year students to improve their experience at the University. In addition, she is a part of a national collaboration with Griffith University that seeks to improve nursing student engagement with physiology and pathophysiology teaching at universities.

Research interests

Her research interests include the neurocognitive and cardio-metabolic changes associated with weight loss and the effects of dietary composition on various health outcomes including metabolic and endocrine dysfunction. Dr Cayanan’s future research development is structured towards translational projects for obesity management in clinical settings with collaboration across multiple sites. She endeavors to develop a weight loss intervention for patients with obstructive sleep apnea tailored specifically for delivery by nurses with the intention of translation within the hospital setting.

In addition, Dr Cayanan is investigating the impact of shift work on nutritional preferences and energy intake in nurses with the intention of developing an intervention to target obesity amongst shiftworkers. Dr Cayanan continues to collaborate with the Woolcock Institute of Medical Research, The Brain and Mind Centre, The Boden Institute, The Charles Perkins Centre and is a member of the Sydney Sleep Clinical Trials Network whose goal is to roll out translational programs within hospital settings.
