My research focuses on health economics issues in developing countries. I have a keen interest in financial incentives, impact evaluation, the economic consequences of ill health, equity in health financing, maternal health and, more broadly, the interaction between health and development.

My PhD research was based on an evaluation of a nationwide financial incentive programme for maternal health in Nepal. This interest in financial incentives - both demand and supply-side - has continued with research in India, China and Tanzania.

My current research includes: 1) Understanding and enhancing approaches to quality improvement in small and medium-sized private facilities in sub-Saharan Africa, funded by the Health Systems Research Initiative; 2) Lancet Global Health Commission on primary health care financing; 3) Equi-PMAQ, a MRC-funded health systems research project on pay-for-performance in Brazil; 4) IMPRESS, an NIHR-funded project on the role of hospital management in improving quality of care for small and sick newborns in Malawi; and 5) NEST360.

I supervise PhD students with an interest in health systems research in low- and middle-income countries, strong quantitative skills and a background in economics. My current doctoral students are: Henry Cust, Jessica King, Muntaqa Umar-Sadiq, Jennifer Ljungqvist, Manon Haemmerli, Rym Ghouma, Camilla Fabbri and Stephen Dorgan.
