As a health and development economist based at the Stanford School of Medicine, Dr. Miller's overarching focus is research and teaching aimed at developing more effective health improvement strategies for developing countries.

His agenda addresses three major interrelated themes: First, what are the major causes of population health improvement around the world and over time? His projects addressing this question are retrospective observational studies that focus both on historical health improvement and the determinants of population health in developing countries today. Second, what are the behavioral underpinnings of the major determinants of population health improvement? Policy relevance and generalizability require knowing not only which factors have contributed most to population health gains, but also why. Third, how can programs and policies use these behavioral insights to improve population health more effectively? The ultimate test of policy relevance is the ability to help formulate new strategies using these insights that are effective.
