The committee will define meeting objectives, produce an agenda and identify appropriate speakers. The workshop will focus on exploring (1) the policy implications of racial/ethnic and socio-economic disparities in the U.S. population and the role of researchers; (2) the state of science and evidence in population health; and (3) the status, gaps, and future frontiers in building common ground between population health science and policy. A proceedings of the presentations and discussions at the workshop will be prepared by a designated rapporteur in accordance with institutional guidelines.
