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. Since 2009, she has delivered 16 invited lectures at International Conferences. 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
