Prof. Susan WalkerProfessor of Nutrition
Professor Susan Walker is a global leader in the research, implementation, and scale-up of programmes to improve children’s health, cognitive, and socio-emotional development in LMICs. Prof Walker is Professor of Nutrition and was formerly the Director of the Caribbean Institute for Health Research (2012-20) at the University of West Indies. During her tenure she initiated increased collaboration among the four research units that comprise CAIHR and extended international partnerships. She currently leads the Child Development Research Group within CAIHR.
Prof Walker has led technically outstanding, multi-country, and policy-focused research. She led the research team on ‘Reach Up’, the internationally known early childhood development programme. Reach Up has been rigorously evaluated, and adapted for delivery in 18 countries including Brazil, China, Colombia, Guatemala, India, Jordan, Lebanon, Kenya, Turkey, and Zimbabwe. It has also been adapted as a national programme in Bangladesh, Jamaica, and Peru. The expansion of Reach Up has been achieved through partnerships with in-country research and implementation teams and with international organisations (e.g. International Rescue Committee, Africa Early Childhood Network, Inter-American Development Bank). Following a meeting convened with partners and supported by the LEGO Foundation, a Reach Up global community was established comprising practitioners, researchers and policy makers to provide a forum to support implementation and scaling. Professor Walker received the Vice Chancellor’s Award for Excellence in Research in 2007.
Prof Walker has been highly influential in shaping the global research and policy agendas on child development. She led the follow-up through to age 31 years of the Jamaica supplementation and stimulation trial showing benefits for adult income, education, and mental health from the home-visit stimulation intervention. This work has provided critical evidence on the potential long-term gains from early intervention and has been used by several international agencies to demonstrate the need to scale early childhood development services. Prof Walker was a coordinator on the Lancet 2013 series on Maternal and Child Nutrition, and lead author on papers in the Lancet child development series, on risk factors for child development (2007) and inequalities in early childhood (2011) in developing countries. She has longstanding relationships with the Social Protection team at the Inter-American Development Bank and the World Bank Early Years group. Prof Walker was a member of the WHO Guideline Development Group on improving early childhood development and the National Academy of Sciences Forum on Investing in Young Children Globally.
