Dr Sarah Bath
Dr Sarah Bath is a Lecturer in Public Health Nutrition at the University of Surrey. She is a registered dietitian with the Health and Care Professions Council. She worked as a clinical dietitian in the NHS for 18 months.
Sarah has been researching iodine in the UK since 2006. Under the supervision of Professor Margaret Rayman, she completed her PhD on “iodine status of UK pregnant women and its implications”. She recently held an MRC Population Health Scientist Fellowship (2013-2016) to investigate “Iodine status in pregnancy and child neurodevelopment: the influence of genetic variation, selenium status and thyroid function on the relationship”.
