Stewart is Director of the Behavioural Science Practice at Nesta.
Stewart has joined us from the Behavioural Insights Team (BIT) where he was Co-Head of International Programmes in the London office. His work at BIT focused on the application of behavioural science to public policy with international organisations and foreign governments, including the World Bank, the United Nations Development Programme and the UK Foreign, Commonwealth & Development Office.
Stewart managed a number of high-profile trials for BIT including interventions that doubled adherence to tuberculosis medication in Moldova, tripled tax receipts from late taxpayers in Guatemala, and increased financial inclusion behaviours in Mexico. He also supported the creation of several new behavioural insights units around the world, including the Centre for Behavioural Studies in Tanzania.
Prior to joining BIT, Stewart evaluated behavioural adaptations to water and sanitation projects in India. He completed his PhD in Economics at the University of Bristol in 2016.
