  • Chair of the department of clinical genetics at Fox Chase Cancer Center

Dr. Daly is director of the risk assessment program which evaluates preventive approaches to breast and ovarian cancer, prostate cancer, colorectal cancer and skin cancer. Her primary areas of research include the epidemiologic and genetic aspects of breast and ovarian cancer and the translation of this information into effective cancer control approaches.

Dr. Daly serves as the site principal investigator of the NSABP breast cancer prevention trials (P1 and STAR). Her research into the communication of genetic risk for breast cancer within families has identified several important socio-cultural correlates of successful communication. Through the Fox Chase ovarian SPORE grant, Dr. Daly has initiated studies of ovarian cancer screening modalities, quality of life after prophylactic surgery and serum biomarkers of breast and ovarian cancer risk. As principal investigator of the Cooperative Family Registry for Breast Cancer Studies, she is collaborating with institutions worldwide to study the patterns of familial breast and ovarian cancer, gene-environment interactions and the development of newl, genetic-based therapeutic and preventive strategies.

Dr. Daly is a leader in the design of educational programs in cancer genetics and cancer risk for both high risk individuals and for their healthcare providers. She is the past president of the American Society of Preventive Oncology.
