Professor Visvanathan has an international reputation in the research area of nutritional frailty. She is especially interested in the provision of quality health care to prevent the impact of frailty (e.g. falls and fracture) as well as improve the wellbeing, function and quality of life of frail, older people and consumers with dementia. She is also interested in research that is likely to translate into improved clinical practice.
Professor Visvanathan is Clinical Director of the Aged & Extended Care Services at the Queen Elizabeth Hospital (& Basil Hetzel Institute), Central Adelaide Local Health Network since 2005.
She is Director of the Adelaide Geriatrics Training and Research with Aged Care (G-TRAC) Centre, which which include an innovative partnership project between the University of Adelaide and Resthaven Inc. at Paradise. GTRAC is a collaborating partner of the South Australian Advanced Health Research and Translation Centre (Health Translation SA).
Professor Visvanathan is Project Lead to the NHMRC Centre of Research Excellence in Frailty and Healthy Ageing, a global network focused on frailty research to improve clinical care for older people, lead out of the Basil Hetzel Institute/The Queen Elizabeth Hospital.
She is also Associate Investigator with the University of Adelaide School of Medicine's NHMRC Centre of Research Excellence Translating Nutritional Science to Good Health based at the Royal Adelaide Hospital campus and the South Australian Health and Medical Research Institute (SAHMRI).
Professor Visvanathan is Chief Investigator and a current executive committee member to the Registry of Senior Australians, based at SAHMRI as part of the Health Translation SA.
Professor Visvanathan is a current board member of Resthaven Inc..
