Area of Interest
The Troester laboratory studies breast cancer and benign breast disease using genomic, molecular pathology, and epidemiologic approaches. Much of Troester’s research focus has been on understanding interactions between the environment and breast genomics. Troester directs the Center for Environmental Health and Susceptibility and has led a Breast Cancer and the Environment Research Program. She is Co-Principal Investigator on the Carolina Breast Cancer Study (CBCS), a study of breast cancer epidemiology and biology focused on understanding breast cancer disparities and she is Co-Leader of the Lineberger Comprehensive Cancer Center’s Cancer Epidemiology program. She has extensive experience working in consortia, including the African American Breast Cancer Epidemiology and Risk (AMBER) consortium, the Breast Cancer Association Consortium (BCAC), and the Cancer Genome Atlas project. A common theme throughout her work is integrating genomic data and molecular biology with human studies of breast cancer etiology and progression.
