My research uses insights and methods from economics to study a wide range of questions concerning health systems in low- and middle-income countries. I have a keen interest in financial incentives, impact evaluation, the economic consequences of ill health, equity in health financing, maternal and newborn 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, Tanzania and Brazil.

Current and recent research projects include: 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, Muntaqa Umar-Sadiq, Jennifer Ljungqvist, Rym Ghouma, Camilla Fabbri, Stephen Dorgan, and Charlotte Ward.
