Aifric O’Sullivan (BSc, MSc, PhD) is an Assistant Professor in the UCD School of Agriculture and Food Science and PI in the UCD Institute of Food and Health. Her research aims to understand interactions between diet and metabolism that define nutrition phenotypes across the lifespan. Over the past 5 years she has focused on two key areas within the context of this overarching aim 1) to understand the diet-metabolism linkages in early life that impact healthy growth and development in high and low-income countries and 2) to develop phenotyping methods and apply phenotyping with a view to develop personalized nutrition. Current and previous projects include a variety of methods such as diet and lifestyle questionnaires, biofluid collection and analysis, and human interventions in different and challenging environments and life-stages. She 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).
