With funding by the Robert Wood Johnson Foundation, Professor S (Subu) V Subramanian, PhD, and Harvard Pop Center postdoctoral fellow Rockli Kim, ScD, plan to pursue a line of study that could lead to a fundamental shift in the way that population health research is conducted in the future. In their proposed project Novel approaches for investigating treatment heterogeneity: An application to Head Start Impact Study, the researchers will set out to develop a refined approach to quantifying health and well-being that incorporates individual heterogeneity into average assessments, potentially resulting in a more efficient and accurate way to assess the effectiveness of health-related interventions.
