Dr. Pierce has dedicated her career to the treatment of breast cancer patients. Her research focuses on the use of radiotherapy in the multi-modality treatment of breast cancer, with emphasis on intensity modulated radiotherapy in node positive breast cancer, the use of radiosensitizing agents, and the outcomes of women treated with radiation for breast cancer who are carriers of a BRCA1/2 breast cancer susceptibility gene.
