Previous research employment 


World Bank 5 years

Conducted research in economics and behavioural sciences, in particular quantitative and qualitative evaluations of the causal effects of public policies and reforms (on health, poverty reduction, education, labour, energy topics etc.) for countries across the world – with the research used to inform the design of government policies and improve their effectiveness; conducted a range of other data analyses and analytical work on inequality, distribution and ethical topics; conducted workshops on ‘Monitoring and evaluation of public policies using experimental data’ for academics and government officials; and prepared dozens of government policy reports (including their design, data analysis and write-up) to inform public policy decisions on a range of topics – e.g. skills in Cambodia, education in Ghana, female empowerment in Latin America and employment in the Republic of Congo
