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. Prior to this, 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. He also coordinates the Agriculture and Health Research Platform (AHRP) – an initiative of the CGIAR, led by IFPRI, that encompasses partnerships with several health organizations, notably the World Health Organization (WHO). 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.
