Biostatistics Branch

Developing statistical methods for epidemiology and collaboration on epidemiology studies

Investigators in the Biostatistics Branch (BB) develop statistical methods and data resources to strengthen observational studies, intervention trials, and laboratory investigations of cancer.

Research Mission

BB's research mission is to contribute to the understanding of cancer etiology and the improvement of public health through the development and application of quantitative methods.  BB investigators frequently serve as consultants on major studies across DCEG.  Learn more about BB research areas.


BB offers opportunities for post-doctoral research in statistical methods for epidemiologic research, genetic epidemiology, and risk assessment, and for projects in analytic and descriptive epidemiology. Post-doctoral fellows also have an opportunity to collaborate on important epidemiologic studies, many of which include molecular and genetic components. Meet our current BB fellows and learn about BB research training opportunities.

Tools and Resources

BB investigators develop statistical and computational tools for epidemiologic and laboratory studies, and distribute those tools to collaborators and the greater scientific community. Learn more about BB tools and resources.


Branch investigators are key participants in large, complex, interdisciplinary studies in collaboration with scientists throughout the NCI and NIH, and with investigators and public health officials at other government agencies and academic and research institutions in the U.S. and abroad.
