EGRP's Organizational Structure

Our organization consists of the Office of the Associate Director (OAD) and five Branches that oversee and facilitate research to understand the determinants of cancer occurrence and outcomes in human populations.


Choose a branch from the chart below for examples of EGRP’s interests in these areas, contacts for scientific program directors, and ongoing activities.


The Office of the Associate Director (OAD) develops and implements the mission and scientific and strategic agenda of the Epidemiology and Genetics Research Program (EGRP). The OAD integrates and coordinates the activities of the component Branches by establishing program priorities, allocating resources, staff, and assignments; and manages scientific activities and portfolios that cross Branch boundaries.
