Sarah is a social scientist working in the field of public health nutrition and child health. She is passionate about producing policy-relevant research that helps to understand what improves the health and wellbeing of New Zealand children.
Sarah works as a research fellow at the Centre for Longitudinal Research - He Ara ki Mua on New Zealand’s contemporary longitudinal study Growing Up in New Zealand. She also undertakes HRC and government funded research on a variety of public health nutrition topics. Her PhD was on the potential for early childhood education services to assist with obesity prevention and has been used to inform obesity prevention policy.
