Research interests

My research interests cover all aspects of the epidemiology of hereditary breast, ovarian and endometrial cancer, with a focus in prediction of breast/ovarian cancer risk and outcomes for the high-risk population.

My current focus includes male breast cancer, hereditary prostate cancer, BRCA-associated metastatic breast cancer, and quality of life of hereditary cancer patients.
