Joy Lawn, Professor of Maternal, Reproductive and Child Health Epidemiology at the London School of Hygiene & Tropical Medicine, is one of the world’s leading experts on perinatal health. She has made seminal contributions on national and global health estimates, notably the most authoritative estimates for stillbirths and neonatal conditions, and the design and evaluation of integrated maternal, newborn, and child care services at scale, especially in sub-Saharan Africa. Professor Lawn developed the epidemiological evidence and original research for policy and programming to lead change for the global burden of 2.8 million neonatal deaths, 2.7 million third trimester stillbirths, and for prematurity.
