My work broadly investigates the drivers of population health improvements in developing countries. I study how economic, political, and natural environments affect population health. I use a mix of experimental, econometric, qualitative, modeling, and demographic tools to produce insights and strategies for improving health. A sample of current projects address the following questions:•What role does US foreign aid play in reducing mortality and improving equity in developing countries? •What forms of engagement in health improvements - social marketing, public health interventions, or community empowerment, for example - work, and which do not? •What effect do malaria control programs have on child mortality? •What combination of prevention strategies are most cost-effective for Africa’s HIV epidemic?•What is the evidence that foreign aid for health is good diplomacy? •Which populations are most vulnerable to the effects of climate conditions on the availability of food?
My research interests involve understanding the relationship between policies and health outcomes in developing countries. I explore how decisions about foreign assistance for health are made, and how those decisions affect health and health delivery systems in recipient countries. I further explore issues of resource allocation in low and middle-income countries through disease modeling and cost-effectiveness analyses.
