I am an Assistant Professor in Behavioural Science in the Department of Psychological and Behavioural Science, London School of Economics. I am also a Research Associate at the Centre for Economic Performance, London School of Economics, and at the Wellbeing Research Centre, University of Oxford. I am an applied economist: my research fields are behavioural economics and wellbeing, policy and programme evaluation, and applied panel and spatial analysis. I obtained my PhD in Economics from the Paris School of Economics. My research looks at how our environment affects our lives – specifically our behaviour, health, and (ultimately) our wellbeing. I am also interested in using nudges to increase pro-environmental behaviour. My work is aimed at improving evidence-based policy on how to improve these outcomes in a cost-effective manner. I am a frequent advisor to international organisations such as the World Bank or the Organisation for Economic Co-operation and Development (OECD). I also advise national governments, for example, on how to use wellbeing data for policy analysis and appraisal. For my work, I have been awarded the Young Economist Award (FEEM Award) by the European Economic Association.
