Home | Person | Hri Member | Dr Eibhlís M. O’Connor

Eibhlís O’Connor is a Registered Human Nutritionist (RNutr with the UK Association for Nutrition), Lecturer in Human Nutrition and Course Director of the BSc. Food Science and Health programme in the Department of Biological Sciences, UL. She has a BSc and PhD in Nutritional Sciences from University College Cork (UCC). Her research interests include the role of novel, vitamin-K dependent proteins in health and disease, and specifically those involved in bone metabolism, cognition, glucose regulation and cardiovascular health. She also has a keen interest in how diet can impact and modulate the gut microbiota and thus impact health in specific population groups. Eibhlís lead a US Allen Foundation funded project analysing dietary and microbiota-derived vitamin K and its relationship with inflammation and cognition in older individuals and was National Coordinator of the Malnutrition in the Elderly (MaNuEL) Knowledge Hub, a collaborative project involving 22 partners across 7 European Countries (under the JPI HDHL initiative). Eibhlís is a Faculty Member of the Alimentary Pharmabiotic Centre, (APC) UCC and is involved in a number of interventions investigating how diet can modulate the gut microbiota for health in specific population groups. She is the lead UL PI and coordinator of the ImmunoMet and FIBREMET projects, respectively (both Dept. Agriculture, Food and the Marine funded) which are collaborative projects (with APC, UCD and Teagasc) designed to investigate the effect of dietary manipulation on microbiota diversity for controlling immune function and metabolism in diabetes and inflammatory bowel disease cohorts.
