Board Certifications

Anatomic Pathology; Clinical Pathology

As a board-certified pathologist with a specialization in breast pathology, I perform microscopic examination of breast biopsies and surgical specimens and make diagnoses that help guide treatment decisions for our patients. I am proud to be part of the multidisciplinary team providing breast cancer patients with comprehensive and coordinated care.

I am interested in the molecular and genetic mechanisms of breast cancer development, progression, and response to treatments. My current research is focused on triple negative breast carcinoma — a subgroup of breast cancer that does not express estrogen and progesterone receptors, or the human epidermal growth factor receptor 2 (HER2). I also work closely with my colleagues from surgery, medical oncology, and radiation oncology on a variety of clinical studies in breast cancer.


Doctors at Memorial Sloan Kettering work as teams, with specialists from all different areas. This allows us to consider all your needs together, and to give you the best possible care.

Clinical Trials
