Aifric O’Sullivan (BSc, MSc, PhD) is an Assistant Professor and Associate Dean for International Programmes in the UCD School of Agriculture and Food Science, and PI in the UCD Institute of Food and Health. Aifric's research aims to understand interactions between diet and metabolism that define nutrition phenotypes across the lifespan. She uses twin studies to examine the impact of genes and environment on diet and metabolism and the interaction of both. The ultimate goal of this research is to understand inter and intra-individual variability, and why certain people respond or different diets and lifestyles with a view to informing personalised, sustainable nutrition strategies. The majority of her research projects involve the application of metabolomics to explore responses to diet, lifestyle and interventions. Some recent and ongoing projects include: AgriDiet, Understanding agriculture-nutrition linkages in Tanzania; UCD Twin Study, Investigating variation in nutrition phenotypes; ESTEA Twins Follow-up, Investigating nutrition-cognition linkages in childhood; NutriPlus, Inter-individual response to vitamin D supplementation; and SuHeGuide, Personalising food-based strategies to achieve a healthy, sustainable diet. Aifric teaches at undergraduate and postgraduate level and leads a team of researchers which includes PhD students. She is the Vice Chair of the Executive Committee of the UCD Childhood and Human Development Research Centre, a member of the UCD Volunteers Overseas Board of Directors, the Royal Irish Academy representative on the IAP/EASAC Working Group on Food and Nutrition Security and Agriculture, on the Editorial Board for three Nutrition Journals and a member of the Metabolomics Society and the Nutrition Society (UK).
