I am a quantitative, development economist, with over 15 years experience in policy relevant, data driven, research. After completing my doctorate in Economics from Oxford University, where I was affiliated to the Centre for the Study of African Economies, I spent seven years working for a range of international organisations (the World Bank/FAO, the Overseas Development Institute, Oxfam GB, the International Cocoa Initiative, and a 9-year research collaboration with Ghana Strategy Support Programme of the International Food Policy Research Institute) applying my research skills to policy relevant problems.

In September 2017, I decided to return to academia and join LSHTM, first as a research fellow for CEDIL (Centre of Excellence for Impact Development and Learning), an FCDO/UKAID funded research consortium on innovative methods in impact evaluation and evidence synthesis. In 2022, I joined the Faculty of Infectious and Tropical Disease working with the Environmental Health Group. Here, I worked on a World Vision programme to end open defecation in Southern Malawi through a set of sanitation and hygiene activities against which I supported setting up an evaluation design. In May 2023, I moved to the Department of Global Health Development (GHD) working on an ESRC grant which I co-lead with the International Security and Development Centre in Berlin. The grant uses secondary data from ACLED and VACs to etimate the casual pathways from violent societies to violence against children. In GHD I also collaborate on the MIDEQ research hub conducting quantitative analysis on corridors of South South migration.
