Board Certifications

Anatomic Pathology

I am board-certified pathologist with expertise in breast pathology. I am also a physician-scientist focused on the study of breast cancer. As a member of the Breast Disease Management Team, I work closely with a multidisciplinary team to provide comprehensive care for people with breast tumors. My research focuses on the study of the genetic alterations in breast cancer, particularly of special histologic subtypes, and on the identification of new cancer genes through the study of rare tumors. Ultimately, my goal is for this knowledge to help develop new strategies for caring for people with breast cancer.
