Genetic Epidemiology Branch

Exploring gene-environment interactions in determining cancer risk

The Genetic Epidemiology Branch (GEB) conducts studies to evaluate the interaction of host and environmental factors in cancer causation.

Research Mission

GEB's mission is to design and conduct interdisciplinary clinical, epidemiologic, genetic, and laboratory studies of persons, families, and populations at high risk of cancer. GEB’s roots are in family studies, and a large proportion of our time and resources are still devoted to evaluation of kindreds. In addition to family studies, we conduct interdisciplinary studies in larger populations to evaluate the relevance of genetic variations in cancer etiology, where GEB investigators apply genetic and molecular epidemiologic approaches to study cancers of the lung, hematopoietic system, skin (melanoma), esophagus, stomach, and breast.
