Postdoctoral Fellow

Faculty of Health and Medical Sciences


Dr Vida Bitarafan is an early career researcher with an outstanding track records in the research area related to the effects of dietary compounds on functions of the gastrointestinal tract in health, obesity or type 2 diabetes. She is a BSc nutrition graduate of Islamic Azad University (Tehran, Iran) and MSc nutrition graduate of Tehran University of Medical Sciences and Health Services (Tehran, Iran). Her PhD was pursued with Centre of Research Excellent (CRE) in Adelaide Medical School, Faculty of Health and Medical Sciences, University of Adelaide and completed on June, 2020. Since completing her PhD, she has been working as a postdoctoral researcher, in Prof Christine Feinle-Bisset's research group, at CRE.

Dr Bitarafan's research area is focused on characterising the pivotal role of the gastrointestinal tract, particularly the role of dietary nutritive and non-nutritive compounds (i.e. bitter substances), in appetite and blood glucose regulation in humans. In order to achieve these accomplishments, she has been heavily trained and involved in using sophisticated research and medical technologies to study various aspects of gastrointestinal responses, e.g. high-resolution manometry, gastrointestinal ultrasound, breath-testing techniques and etc. Her research has made contributions to current understanding of mechanisms underlying conditions such as obesity and type 2 diabetes (both major health issues which have increased markedly worldwide in recent years, and are associated with substantial health, economic and psychosocial cost) and concepts of how dietary compounds interact with the function of the gut in the regulation of appetite (and overeating) on the one hand, and blood glucose on the other. These discoveries are likely to result in ground-breaking, new knowledge that will be fundamental for the development of novel strategies, including commercial outcomes, with major implications for the prevention, management and treatment of disorders, including obesity and type 2 diabetes.
