About Me

I am a surgical pathologist who specializes in breast pathology. My goal is to provide high quality care by making accurate and timely diagnoses for people with breast cancer. I also use my expertise to provide important information that can help them understand the likely course of their disease. My research interests are focused on the clinical, morphologic, and molecular features of breast cancer. I enjoy working in a large academic cancer center with numerous opportunities for teaching and mentoring pathology trainees.
