I am currently Assistant Professor in Health Research at the School of Nursing and Midwifery at Trinity College Dublin. Formerly, I was a Senior Research Fellow and Biobank Manager with The Irish Longitudinal Study on Ageing (TILDA) at the School of Medicine, Trinity College Dublin and Mercer"s Institute for Successful Ageing (MISA) at St. James"s Hospital, Dublin. I hold a PhD in the genetic epidemiology of cardiovascular disease from the Royal College of Surgeons in Ireland (RCSI) and a B.A. (Mod) in Natural Science, specializing in genetics, from Trinity College Dublin. My research interests are focused on the biology of ageing and age-related disease phenotypes including CVD, frailty and disability. My research aims to investigate biomarkers that best capture those who are experiencing accelerated biological ageing and who are therefore at risk for declining health and age-related disease. This information is utilized to inform disease prevention and management strategies, and to improve health and social care policy and service planning. I have published >60 peer-reviewed publications on studies of ageing, epidemiology, molecular biology, immunology, and genetics. As principal or co-investigator, I have received grant funding of €2.1 million from national agencies and international grant funding of €4.5 million (€850,000 to the Irish component) from the US National Institutes of Health. I have taught and supervised undergraduate and postgraduate students to PhD level. Currently, I teach on the Postgraduate Certificate on Advanced Ageing and Frailty Studies at Trinity College Dublin. I am a member of the EUGMS SIG on Frailty and Resilience in Older People, the NIH Biomarker Network, and the Irish Frailty Network. I am associate editor with the journal BMC Geriatrics and served as a member of the national executive committee of the Irish Gerontological Society (2016-2022).

Summary
The unprecedented global increase in life expectancy over the past century has lead to a rapidly expanding ageing population, placing ever higher demands on publicly-funded healthcare resources in Ireland, North and South. Current trajectories indicate that such demands are unsustainable. Early identifiers of declining health will be central to measuring health risk. The European Innovation Partnership on Active and Healthy Ageing has highlighted frailty as key to seeking a two year increase in healthy life years by 2020. Resilience and frailty represent opposite ends of a spectrum of decline from robust health to profound functional dependence. Frailty is a driver of functional and cognitive decline, predicting multi-morbidity, disability, increased health care utilisation and mortality (Fried et al, 2001, 2004). However, frailty can be ameliorated by early detection and intervention. Data from The Irish Longitudinal Study of Ageing (TILDA) will be used to track transitions along the frailty spectrum and investigate how frailty-related biomarker profiles of physical, cognitive and psychological health at baseline (Wave 1) change and predict frailty during follow-up (Waves 2 and 3). North-South comparisons between the prevalence and characteristics of frailty using Wave 3 of TILDA and Phase 1 of the Northern Ireland Cohort for Longitudinal Ageing (NICOLA), which coincide during 2014. Will be performed. Elucidating frailty-related risk factors and resource demands in the ageing population will help to identify: (1) new evidence-based targets for pre-clinical frailty detection and intervention, and (2) specific needs that will be vital in delivering efficient, effective healthcare services and increasing healthy life-years into the future

My research interests are focused on the biology of the ageing and age-related disease phenotypes including CVD, frailty and disability. I am also interested in maintaining resilience and intrinsic capacity as we age. My research aims to investigate biomarkers (genetics, epigenetics, metabolites, proteins, microbiomes and objective health measures) that best capture those who are experiencing accelerated biological ageing and who are therefore at risk for declining health and age-related disease/phenotypes. This information is utilized to inform disease prevention, detection and management strategies, and to improve health and social care policy and service planning. Also, this work will raise public awareness of frailty on the island of Ireland.
