Caoileann Murphy
Postdoctoral Fellow – Nutrition and healthy ageingResearch Interests
Caoileann is currently based in Australian Catholic University Melbourne on outgoing phase of fellowship.
My research investigates lifestyle interventions to support healthy aging. In particular, my research focuses on nutrition and exercise strategies to prevent and treat age-related declines in muscle strength and mass (termed sarcopenia) and, more recently, osteoporosis.
Current Projects
Nutri-Age:
Nutri-Age aims to investigate whether nutrients found in fruit and vegetables can help to offset the unfavourable changes in muscle and bone associated with ageing in older adults. In addition, Nutri-Age aims to provide new insights into why older adults in Ireland choose the foods that they do and into their attitudes towards food products that are fortified with health-promoting nutrients for healthy ageing.
