Research Training Opportunities in Hormonal and Reproductive Epidemiology


The Hormonal and Reproductive Epidemiology Branch (HREB) conducts research to identify risk factors for hormonally related tumors (e.g., breast, ovarian, endometrial, cervical, testicular). Another major area of research is focusing on the role of the human papillomaviruses in the etiology of tumors. Emphasis is also being given to defining risk factors for several rare malignancies, including cancers of the liver and biliary tract.

Fellows in HREB:

  • collaborate and learn from investigators in a world-renowned research program;
  • have access to large population-based studies with biological specimens;
  • learn how to validate biomarkers determined by new molecular techniques;
  • apply new biomarkers to large epidemiological studies;
  • have opportunities to initiate new investigations and to compete for funding; and
  • are compensated comparable to or exceeding most entry-level academic positions.

For application details, see below. To discuss potential research opportunities, you may contact branch investigators directly. Meet fellows in the Hormonal and Reproductive Epidemiology Branch.


Postdoctoral fellowships: Individuals must either hold a doctorate degree in or be enrolled in a doctoral program in epidemiology. Individuals with a strong understanding of biological processes are encouraged to apply. Fellowship training is for up to 5 years under the supervision of NCI senior scientists.

Predoctoral fellowships: Individuals must either be enrolled in a doctoral program with the desire to complete their dissertation in HREB, or have a Master's degree in a field relevant to HREB.

Application Process

Predoctoral and postdoctoral fellowship applications in the branch are accepted on an ongoing basis. See the Fellowship Information for an overview, qualifications, and application details. Branch-specific opportunities are listed below.

Training Opportunities

Examples of research opportunities include:

  • Assessment of gene-environment interactions in multiple large population-based studies
