Dr Murphy is currently a NHMRC (Senior) Industry Research Fellow in the Nutritional Physiology Research Centre, researching the area of healthy foods and nutrients and effect on cardiovascular health and cognitive function.
The primary goal of her research is to understand the impact of dietary factors on cardiovascular health and cognitive function and psychological wellbeing using randomised controlled trials. More specifically she aims to provide scientific substantiation of the health benefits of healthy foods and nutrients to help reduce the physical and mental suffering from cardiovascular disease. Her recent work has focussed on healthy foods including low fat dairy, meat-based protein diets, bioactive nutrients including antioxidants and omega-3. Her research on dairy and cardiovascular health was recognised by the Heart Foundation in 2010 where she was asked to provide expert opinion on the Heart Foundation position paper ‘The relationship between milk fat and CVD risk’. With the award of an NHMRC Project grant in 2013, her current work is evaluating the effect of an Australianised Mediterranean diet on cardiovascular health and cognitive function in Australians aged 65years and above in a 6 month dietary intervention trial. With the award of a PorkCRC Grant she is studying the effect of an energy restricted protein/lower carbohyrate diet with exercise on glycemic control and cognitive function in adults with type 2 diabetes. She has returned to work on a part-time basis post two periods of maternity leave.
Dr Murphy is a recipient of 23 research awards including the South Australian Young Tall Poppy Award (2009), Australian Academy of Science Travel Fellowship (2008), International Society for the Study of Fatty Acids and Lipids Young Researcher Award (2004/2006), Nutrition Trust of Australia Fellowship, RMIT International Scholarship (2001), the Roger Pysden Memorial Fellowship (2000), Unilever Australia Foods Scholar (2000), Cayman Chemical Company Scholar (2001, 2002, 2004), Pharmalink International Scholar (2001-2004), Effem Foods Scholar (2000, 2002), Australian Atherosclerosis Society Scholar (2002) and a Nutrition Society of Australia Scholar (1999, 2002).
Dr Murphy has organised, convened and chaired a number of highly successful scientific meetings and symposia for the Australasian American Oil Chemists Society and Nutrition Society of Australia and have been successful in engaging students in these activities.
Dr Murphy is President of the Australasian American Oil Chemists Society, Honorary Treasurer of the Nutrition Society of Australia and a member of the International Society for the Study of Fatty Acids and Lipids. She is also a Registered Nutritionist and a Certified Clinical Research Coordinator (ACRP).
Dr Murphy is currently supervising three PhD students.
