Assistant Professor
Thank you for your interest in the University of Rochester Department of Imaging Sciences Breast Imaging Fellowship. Our one-year fellowship offers comprehensive, high-volume training across the full spectrum of breast imaging in a supportive and collaborative academic environment. With experience across both hospital and outpatient settings, fellows work alongside dedicated breast imaging faculty while developing the clinical expertise, procedural skills, and confidence needed for a successful career in breast imaging.
Fellows also participate in a variety of educational conferences, including the weekly Multidisciplinary Breast Tumor Conference at the Wilmot Cancer Institute Pluta Cancer Center and have multiple opportunities to engage in research and pursue individual academic interests.
We will be participating in the fellowship match. Prospective fellowship candidates should register with the Radiology Match, which is sponsored by the Society of Breast Imaging, and managed by the National Resident Matching Program.
Two positions are available per year, and we are seeking enthusiastic candidates. For more information about the Breast Imaging fellowship program, please contact our fellowship coordinator, ISFellowships@urmc.rochester.edu..
