Website for research group; Lorraine Brennan (BA, PhD) is a Conway Fellow and a PI in the UCD Institute of Food and Health. Her research interests revolve around metabolism and altered metabolic pathways in health and disease. She leads a metabolomics research group in UCD and is instrumental in the development of metabolomics for nutritional research. Areas currently under development include (1) the use of a metabolomic approach to identify novel biomarkers of dietary intake and (2) the use of metabolomic signatures ("metabotypes") to identify responder's to dietary interventions in a move towards personalised nutrition. Lorraine is a recipient of a European Research Council (ERC) Consolidator grant. She is a partner in the FP7 projects NutriTech and Food4me. She is a PI in The National Nutrition Phenotype Database where she was responsible for the metabolomics data. She represents the Irish Nutrigenomics Organisation (JINGO) in the Joint Programming Initiative (JPI) ENPADASI. She is a partner in the Joint Programming Initiative (JPI) Biomarker Initiative. She has published over 80 peer-reviewed publications including publications in leading journals such as Nature, Diabetes and Diabetalogia. She regularly serves as a reviewer for international journals and since 2010 she is serving as an academic editor in PLoS One. Professor Brennan is actively involved in undergraduate teaching and delivers a range of lectures to Human Nutrition and Medical students. She is secretary of the Irish Nutrition Society Executive. In September 2014, she was appointed as co-Director of the European Nutrigenomics Organisation (NuGO) ( Professor Brennan has a strong interest in linking research and teaching and in 2014 was appointed a UCD Teaching Fellow to explore these links ( Her full publication list is available at: For examples of research projects see the following podcasts:
