I specialise in impact evaluations of Global Development and Health programmes using randomised, quasi-experimental and mixed-methods designs, systematic review and meta-analysis. At LSHTM I work with the Pathfinder project (climate and health co-benefits), the Environmental Health Group, and the Action Against Stunting Hub. I work closely with global partners in evidence synthesis including Campbell South Asia, Cochrane and am elected Co-Chair of the Campbell Collaboration Climate Solutions Coordinating Group. I am also a Methods Editor with Campbell Systematic Reviews and the Journal of Development Effectiveness. Previously, I founded the Systematic Reviews Programme and London Office of the International Initiative for Impact Evaluation (3ie), based at London International Development Centre, where I worked for 10 years, and was later seconded to the 3ie Evaluation Office based in New Delhi. I have worked for extended periods at the Ministry of Finance and Economic Planning in the Government of Rwanda in Kigali, the World Bank's Independent Evaluation Group in Washington, DC, the UK National Audit Office and the Poverty Research Unit at Sussex University. I have conducted assignments for the Asian Development Bank, Dasra Foundation, DFAT, DFID, FCDO, the Economist Intelligence Unit, Global Affairs Canada, the International Finance Corporation, the Netherlands Ministry of Foreign Affairs, Save the Children, Sightsavers, USAID and the World Health Organization among others. I hold a PhD in Impact Evaluation of Infectious Diseases and Public Health from LSHTM, where I studied under Professor Sandy Cairncross and Edoardo Masset, MA Development Economics from the University of Sussex, and BSc Economics from the University of York.

I co-direct London International Development Centre's Programme Evaluation Short-Course. I co-organise IDM215 WASH Distance Learning Module. I teach on Environment, Health and Sustainable Development, Environmental Epidemiology and Introduction to Health Economics MSc modules.

I currently have one PhD (DrPH) student (Rose NDulu Ndolo), regularly supervise MSc students, and am happy to speak to prospective Masters or PhD students.


I am interested in rigorous empirical policy research that answers relevant questions for decision making. The methodological focus of my work includes causal methods of impact evaluation, including randomised field trials and quasi-experimental approaches like discontinuity designs, small-n qualitative impact evaluation methods, the critical assessment of these studies, systematic reviews, statistical meta-analysis, and the use of mixed methods. I have published research on a range of topics including aid effectiveness, climate and health, environmental health (primarily water, sanitation and hygiene, WASH), maternal and child health and nutrition, and smallholder agriculture.
