Sarah CrozierView profile
Associate Professor
Sarah Crozier is an Associate Professor of Statistical Epidemiology at the MRC Lifecourse Epidemiology Centre within the Faculty of Medicine at the University of Southampton. She specializes in statistical methods applied to developmental epidemiology and nutritional science, with particular expertise in cohort study design and analysis. Her educational background includes a Mathematics degree from the University of Warwick and an MSc in Statistics with Applications in Medicine from the University of Southampton. She completed her PhD under Professor Hazel Inskip at the MRC Lifecourse Epidemiology Unit, focusing on multivariate analysis of dietary data and derivation of 'prudent' diet scores. Dr. Crozier's research centers on the Developmental Origins of Health and Disease (DOHaD) framework, with specific focus on how maternal health behaviors before and during pregnancy influence offspring development. Her work examines women's health behaviors, dietary patterns analysis, childhood adiposity, and advanced growth modeling methods. She investigates psychological and socio-economic pathways between food environments and dietary patterns among women and children, particularly through nutrition-based initiatives aimed at reducing health inequalities. Analysis of her recent publications (2023-2025) reveals consistent focus on maternal nutrition, childhood development outcomes, and food environment interventions. Her work spans epidemiological methods, nutritional science, and public health policy, with strong emphasis on cohort studies and statistical modeling of longitudinal data. Much of her research connects early life exposures to long-term health outcomes, particularly in bone development, adiposity, and cognitive function. Appointed Statistical Editor of the British Journal of Nutrition and the Journal of Nutritional Science (2019) Dr. Crozier serves as principal statistician on the WRAPPED study, a supermarket intervention examining how product placement affects food purchasing among disadvantaged populations. She actively supervises PhD students including Amelia Grace Bird in Human Development & Health. Her research is supported through multiple collaborative projects including the Southampton Women's Survey, ECON study, and Healthy Start Scheme evaluation, demonstrating strong grant capture and interdisciplinary collaboration. As a key member of the Centre for Developmental Origins of Health and Disease and the Institute of Developmental Sciences, Dr. Crozier contributes to Southampton's internationally recognized research environment in lifecourse epidemiology. Her work with the MRC Lifecourse Epidemiology Centre leverages major cohort resources to investigate critical questions in maternal and child health.
