Board Certifications

Anatomic Pathology; Cytopathology

I am a board-certified pathologist and cytopathologist with a special interest and training in breast pathology. I analyze breast tissue biopsies and surgical specimens in order to determine a diagnosis that will help guide treatment options for our patients.  I enjoy being part of a team who strives to practice diagnostic pathology at the highest level. As an active member of the Global Cancer Disparities Initiatives group at MSK, I lead the efforts to establish quality pathology services in low-to-middle income countries. By developing professional and research collaborations in capacity building projects, I am able to secure effective pathology services, which is essential for cancer care in those countries.
