A key focus of my research is on understanding and improving private sector healthcare provision in low and middle income countries, including provision through pharmacies and drug stores, private clinics and hospitals. I'm interested in understanding the growth of this sector, the incentives private providers face, and consequences for healthcare quality and access, and in evaluating interventions to address this. This has included evaluating quality improvement programmes for private facilities (for example through the SafeCare certification model, and through social franchising), multi-national private sector subsidy programmes for antimalarials (AMFm), and regulation of the health facility and retail sectors. Recent projects include analysis of online pharmacy markets in Kenya and India, the market structure for private sector care provision in Georgia, and the overarching governance of the private healthcare sector.

I also study strategies to improve quality of care in the public sector, including enhancing management of district hospitals through the IMPRESS project, and an evaluation of the Global Fund's Health System Strengthening initiatives.

Finally, I am interested in the potential to enhance the equity of international research partnerships and co-lead the evaluation of LSHTM's EquiPar tool.
