Dr. Butler received her 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, she joined the medical faculty of Yale University School of Medicine in 2009. Her work includes patient care, clinical research, and medical education. As a diagnostic radiologist with expertise in breast Imaging, she is part of the multi-disciplinary team that provides state-of-the-art technology and care to our patients at Smilow Cancer Hospital.

Dr. Butler's areas of research interest include digital breast tomosynthesis and screening breast ultrasound. In addition, she served 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.

Dr. Butler is 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, she 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. She participated in revising the curriculum at the Yale School of Medicine, where she teaches first-year medical students, introducing radiology both as a profession and as a teaching tool in the early years of medical education. She has held visiting professorships at 2 community hospital-based Diagnostic Radiology Residency programs in Connecticut, and she lectures regularly at regional and national CME meetings.
