Effective teaching of residents by our faculty is a priority and is emphasized as an important component of academic life. Resident education is focused on the six ACGME Core Competencies: patient care, medical knowledge, practice-based learning and improvement, systems-based practice, professionalism, and interpersonal and communications skills. Special emphasis is placed on the care of patients participating in national (COG, RTOG, GOG, SWOG, etc.) and intramural clinical trials.

Program Director Dr. David Horowitz is also the director of our medical student education. Residents learn to become mentors in his annual “Resident as Teacher” class and our program is the #1 rated elective rotation experience for Columbia University’s medical students, a ranking we’ve held for the past three years.

Our Department

Columbia University’s Radiation Oncology department has an outstanding research program, strengthened by its collaboration with physicians from the Herbert Irving Comprehensive Cancer Center (HICCC), an NCI-designated facility, as well as with our own internationally recognized Center for Radiological Research (CRR), directed by renowned leaders in the field. We are committed to developing new biological and physical approaches for improving radiation therapy and bringing these advances to the clinic to benefit patients directly. In particular, we are dedicated to understanding the biology of cancer and to applying that knowledge to the design of cancer therapies and prevention strategies.


The New York Presbyterian/Columbia Radiation Oncology Residency Program accepts residency applications exclusively through ERAS and does not participate in SOAP.
