Scientific advances have provided the tools to prevent, test, and treat most of the major threats to human health. However, those tools are either not available or used, particularly in low-resource settings across the globe where the burden of illness is the greatest. The Sundararajan Lab uses implementation science research methods to advance the use of evidence based healthcare in low-resource settings. In partnership with our international collaborators, our mission is to empower communities and laypersons as a means to improving population health worldwide.
