Stuart Gillespie, a senior research fellow with IFPRI, is currently CEO of the Transform Nutrition Research Program Consortium – a six-partner consortium that seeks to transform thinking and action on “the neglected crisis of undernutrition” in Sub-Saharan Africa and South Asia – and Research Director of the LANSA consortium (Leveraging Agriculture for Nutrition in South Asia), both DFID-funded. In recent years, he has led the TANDI project (Tackling the Agriculture-Nutrition Disconnect in India), supported by the Bill and Melinda Gates Foundation, and coordinated the Agriculture and Health Research Platform (AHRP), with support from the International Development Research Center. Between 2001-2010 he specialized in action research on the interactions between HIV and food and nutrition security, and their implications for development policy and practice, having co-founded and managed the Regional Network on AIDS, Livelihoods and Food Security (RENEWAL) based in eastern and southern Africa. Past work has focused on understanding 'what works' in malnutrition reduction, scaling up community driven development, and developing methodologies for community capacity analysis.

A British citizen, Gillespie earned a food science honors degree from the University of Reading, a master's degree and Ph.D. in human nutrition from the London School of Hygiene and Tropical Medicine in 1988. Before joining IFPRI in 1999, he worked with various international agencies, bilateral agencies, and nongovernmental organizations on nutrition policy analysis, information systems development, and monitoring and evaluation.
