Dr Suzanne Barr is a senior Registered Dietitian with particular interests in weight management, diabetes, cardiovascular disease, women’s health and healthcare technologies. She completed her Undergraduate degree in Nutrition at the University of Glasgow, Masters degree in Dietetics at Queen Margaret University, Edinburgh and PhD in Human Nutrition at Roehampton University, London. Suzanne worked clinically within the NHS before undertaking her PhD which investigated dietary management strategies for women with polycystic ovary syndrome (PCOS), including implementing a low glycaemic idex diet to improve insulin sensitivity. Suzanne was previously employed as a research dietitian at King's College London on a large multi-centre gestational diabetes prevention trial (UK Better Eating and Pregnancy Trial (UPBEAT)). Suzanne joined Imperial College London in 2011 as a Senior Teaching Fellow on the MSc in Preventive Cardiology (programme ending September 2018), and now teaches on the MRes Clinical Research (Human Nutrition pathway) in the Department of Medicine (from 2018).
