She has been the research lead on both the Frailty and Biomarker Working Groups within TILDA and also manages the TILDA Biobank, the largest of its kind in the Rep. of Ireland. Dr. O'Halloran holds a PhD in the genetic epidemiology of cardiovascular disease from the Royal College of Surgeons in Ireland and a B.A. (Mod) in Natural Science, specializing in Genetics, from Trinity College Dublin. For over fourteen years, Dr. O'Halloran has conducted research on studies of ageing, health epidemiology, immunology and genetics. Her research interests are in the area of frailty and ageing biology in older adults, including related risk factors (biomarkers) and patterns of service use. She has secured a combined peer-reviewed grant portfolio of €1.7 million, including a NIH, SFI and HRB sponsored awards. She has published >30 peer-reviewed articles in international journals.

Her current research interest is in the biology of ageing, including frailty, falls, resilience and well-being. She has a particular interest in characterizing biomarkers (genes, proteins, metabolites, processes) implicated in these age-related disorders. The goal of her research is to identify early biomarkers for use in screening and intervention in the progression of frailty and investigate patterns of health care use. This work will inform frailty detection/prevention/intervention, frailty-related health service use and provision and raise public awareness of frailty on the island of Ireland.
