Ben D'Exelle is a Professor of Economics at the University of East Anglia (UK). His research aims to improve our understanding of individual behaviour and decision-making, and how this is influenced by social interaction within households and communities. He applies this to a variety of domains, such as health, development, labour, gender, environment, and agriculture. Most of his research is conducted in low- and middle-income countries, driven by the need to develop more effective policies that tackle the most urgent problems in these countries. He makes ample use of experiments, either in the form of randomized control trials, or lab experiments conducted online, in computer labs or in the field. He has completed projects in Uganda, Tanzania, Burkina Faso, Nicaragua, Colombia, and Peru, and is involved in new fieldwork in Bangladesh, Ivory Coast, and the Dominican Republic.

He is affiliated to the Center for Behavioural and Experimental Social Sciences (CBESS), member of CSERGE, a collaborator of the Norwich Institute for Sustainable Development, an IZA fellow, and a full member of the European Development Research Network (EUDN).
