As a dietitian and epidemiologist, I investigate the role of nutrition in healthy ageing and prevention of disease. My research spans two main areas: (1) Examination of dietary and other modifiable factors in relation to disease risk in cohort studies (2) Development and evaluation of interventions to promote lifestyle behaviour change and improve health and well-being. Specifically, I am interested in how plant-based dietary patterns influence age-related functional abilities (physical and cognitive function), cardiometabolic disease, frailty and dementia risk in later life. I am also interested in understanding food insecurity as a social determinant of diet quality and age-related disease. I am recipient of several prestigious awards including The Beeson-CARDI Career Development Fellowship (American Federation of Aging Research). I am a Senior Atlantic Fellow of the Global Brain Health Institute, University of California San Francisco and Trinity College Dublin.
