Occupational and Environmental Epidemiology Branch

Identifying workplace and environmental exposures associated with cancer risk

The Occupational and Environmental Epidemiology Branch (OEEB) conducts studies in the United States and abroad to identify and evaluate environmental and workplace exposures that may be associated with cancer risk.

Research Mission

OEEB's mission is to combine epidemiology, quantitative exposure assessment, and molecular components into multi-disciplinary studies to provide insight into cancer etiology, chemical carcinogenesis, and mechanisms of action. Our main research areas include:

  • Industrial and Occupational Exposures
  • Environmental Exposures
  • Exposure Assessment Methods

Read more about OEEB's research areas and activities.


Training opportunities for junior investigators include planning new projects, participating in ongoing investigations, and analyzing data from studies whose fieldwork is completed. Pre-doctoral and postdoctoral fellows are mentored by senior investigators in the Branch. Meet our current OEEB fellows and find out about research training opportunities.


The breadth of OEEB's occupational and environmental risk factor research offers many possibilities for collaboration with investigators at other government agencies, domestic and international institutions, and academia, as well as training opportunities for young scientists. Collaborations are underway in over 30 states and Puerto Rico in the U.S., as well as over 30 countries in North and South America, Europe, Asia, the Mideast, and Australia.

Tools and Resources

Investigators in OEEB are also engaged in developing innovative tools and approaches for assessing carcinogenic risks from occupational and environmental exposures. Find out more about OEEB tools and resources.
