Dr O’Sullivan’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.
