Promoting health and preventing disease

Improving population health requires a strong focus on preventing disease and strategic decision-making.

The Prevention Policy Modeling Lab evaluates the health impact, costs and cost-effectiveness of infectious disease treatment and prevention programs in the United States. We work closely with collaborators in the National Center for HIV/AIDS, Viral Hepatitis, STD, and TB Prevention (NCHHSTP) at the Centers for Disease Control and Prevention to inform U.S. health policy and guide public health decision-making at national, state and local levels. The models we build incorporate evidence-based prevention strategies, emphasize cross-cutting initiatives and produce results that can be operationalized within healthcare and other sectors.


Our Work

PPML is dedicated to creating models that improve public health decision-making in five key areas: HIV, viral hepatitis, sexually transmitted infections, tuberculosis, and school/adolescent health.

Visualizing outcomes

To promote the translation of results from our modeling studies into policy, the Prevention Policy Modeling Lab has developed a suite of interactive web tools.
