Departments & Organizations

Radiology & Biomedical Imaging: Breast Imaging

Yale Cancer Center: Breast Center

Yale Medicine

Office of Cooperative Research


I received my training in Diagnostic Radiology with a fellowship in Breast Imaging at Northwestern Memorial Hospital, Lynn Sage Breast Center in Chicago, Illinois. After 10 years in private practice in the Chicago area, I returned to academic medicine at Yale New Haven Hospital and joined the medical faculty of Yale University in 2009. My primary role is clinical patient care, and I am delighted to be part of the multi-disciplinary team that provides state-of-the-art technology and care to our patients at the Smilow Cancer Hospital.

My areas of research interest include digital breast tomosynthesis and breast MRI. In addition, I serve as national co-PI for an industry-sponsored clinical trial of opto-acoustic breast imaging, a new functional imaging modality that may improve the diagnosis of benign and malignant breast masses.

I am actively involved in teaching at Yale and within the radiology community at large. After completing a medical education fellowship at the Yale School of Medicine, I founded and directed the Yale Undergraduate Shadowing Program at the Smilow Breast Center, providing pre-medical students with early exposure to the multiple disciplines involved in the diagnosis and treatment of breast cancer. I participated in revising the Yale School of Medicine curriculum, where I also teach first- and second-year medical students, introducing radiology both as a profession and as a teaching tool in the early years of medical education. Finally, I hold visiting professorships at 2 community hospital-based Diagnostic Radiology Residency programs in Connecticut, and I lecture regularly at regional and national CME meetings.
