Our research investigates the impact of select dietary components (in particular n-3 fatty acids) and a Mediterranean-style dietary pattern on cardio-metabolic and cognitive health. We also investigate nutrient-genotype interactions with a focus on the APOE genotype, establishing the aetiology of genotype-health associations and dietary strategies to mitigate the effects of the ‘at-risk’ APOE4 allele. 

Having completed my first degree in Nutrition and Biochemistry at University College Cork (Ireland), I moved to the UK to complete my PhD. I have been based here ever since, apart from a one-year stay at Auckland Medical School (NZ).

I enjoy the outdoors and in particular running, good food and wandering around supermarkets, social and historical fiction, and travel and its planning.

I am Head of the NUTRIGENETICS group within the Department of Nutrition and Preventive Medicine, with our key research interests being:

• Nutrigenetics,
• n-3 fatty acids and cardio-metabolic health, with a focus on plasma lipids, and vascular and hepatic function,
• Cognition and Alzheimer’s disease,
• Aetiology of APOE4 genotype-chronic disease associations,
• Determinants of flavonoid metabolism.

Research approaches

A large proportion of our research involves human intervention trials (RCTs). In addition, we employ a variety of wild-type and transgenic rodent models and cell and molecular techniques to investigate underlying mechanisms, and to inform the foci of our RCTs.

Examples of ongoing RCTs include:

• Apple Tree (ESRC-NIHR funded, 2019-2024): Active Prevention in People at Risk of Dementia through Lifestyle, Behaviour change and Technology to build resilience, 20+ research partners 

• NuBrain (BBSRC-MRC-NIHR funded (UK NRP), 2019-2022: UK Consortium for Optimal Nutrition for Healthy Brain Ageing, Newcastle, Norwich, Edinburgh, Manchester.

• MedEx (Alzheimer’s Research UK-MRC funded, 2018-2021): Diet, physical activity and dementia risk in UK adults: Epidemiology and MedEx feasibility study, Norwich, Newcastle, Birmingham and Aberdeen.

• CANN (Centre of Nutrition Memory and Learning, CNLM, University of Illinois funded, 2015-2020): A Randomised Controlled Trial in ‘At Risk’ Humans investigating the Cognitive Benefits of Combined Flavonoid/Fatty Acid and Underlying Mechanisms of Action: The Cognitive Aging Nutrition and Neurogenesis (CANN) trial (n=240), Norwich, Melbourne, Illinois
