Radiation Oncology Residency Program

Welcome to the Mount Sinai Radiation Oncology Residency Program website and thank you for your interest in our program. We pride ourselves on our ability to successfully train residents for their future Radiation Oncology practice. In addition to providing an excellent clinical experience, we are committed to maintaining an academic environment that promotes basic science and clinical research. To that end, we offer an outstanding training program that includes a broad exposure to patient care, education and research. Our program merges cutting edge technology, compassionate patient care, and a supportive academic environment. Upon completion of the program, physicians are ready to meet the demands of and succeed in an academic center or a private practice.

Additional Opportunities

We encourage current medical students to explore radiation oncology by applying for an elective rotation in our department. We accept applications from students outside of the Icahn School of Medicine via the Visiting Student Application Service (VSAS)

The Icahn School of Medicine at Mount Sinai offers internships, but this requires a separate application process and is not part of the Radiation Oncology application.


You spend a minimum of 36 months in clinical rotations, primarily at The Mount Sinai Hospital in Manhattan. You also do rotations at affiliated institutions such as James J. Peters Veterans Affairs Medical Center in the Bronx, Elmhurst Hospital Center in Elmhurst, New York, and Queens Hospital Center in Jamaica, New York.  In addition, you complete a two-month rotation in pediatric radiation oncology at Memorial Sloan-Kettering Cancer Center. 

You can spend the remaining time in electives such as dosimetry, medical oncology, pathology, radiology, nuclear medicine, and laboratory or clinical research. 

You will learn about the diagnosis and management of malignant diseases such as cancer, and the application of external radiation therapy and brachytherapy to treat these concerns in adults and children. You learn to obtain pertinent information from patient history and physical examination, to review diagnostic and pathologic information, and to present cases to faculty radiation oncologists. You gain experience in the overall management of cancer patients, working with a multidisciplinary team of medical oncologists, surgeons, and other related physicians.

You learn about the principles of and technical aspects of treatment planning and gain exposure to the management of acute effects of treatment. Through involvement in follow-up clinics, you see the late effects of treatment and the management of complications and recurrences.  

We also provide didactic education. Every week, we hold two faculty-led clinical conferences, one radiation physics lecture, and one radiation biology lecture. This is protected time when you can focus on education. In addition, you attend several multi-disciplinary tumor boards weekly.

Daniel Dickstein, MD
Daniel, originally from Westfield, NJ, attended Bowdoin College in Brunswick, ME, where he completed his undergraduate studies in mathematics and biochemistry. He earned his MD at the Icahn School of Medicine at Mount Sinai, where he completed a year of clinical research with Dr. Richard Bakst developing an investigator-initiated trial on hypofractionation for older adults with head and neck cancer. Before returning to Mount Sinai for residency, Daniel completed his internship at Greenwich Hospital, where he also continued his Mount Sinai research, developing another clinical trial with Dr. Bakst investigating the relationship between the oral microbiome and head and neck cancers. While a resident, Daniel became interested in sexual health and treatment-related toxicities in sexual and gender minorities with prostate cancer and general pelvic malignancies. He began working with Dr. Deborah Marshall in her NIH-funded STAR (Sexual Toxicity After Radiotherapy) lab to develop research to improve sexual health outcomes in all cancer survivors regardless of their sexual orientation, recorded sex at birth, and gender identity. He won an ASCO Young Investigator Award for a project that will evaluate the contribution of radiation to problematic receptive anal intercourse after prostate radiotherapy and help identify a dosimetric parameter to be used to prevent this toxicity. Daniel is grateful for the support and guidance he receives from his incredible mentors—it takes a village. Outside of science and medicine, Daniel enjoys watching Netlfix, eating ice cream (usually cookie dough), and talking. A lot.

We seek applicants who are interested in radiation oncology. While we do not require prior experience in the field, we do look favorably on research and clinical rotations that indicate interest in radiation oncology.

We select fellows through the Medicine Subspecialty Match, which is part of the National Residency Match Program (NRMP). You must submit your application through the Electronic Residency Application System (ERAS), along with all supporting documents. We only consider applicants who are registered with the NRMP and only consider applications through ERAS. We require, in addition to the application form, the following materials:

  • Up-to-date curriculum vitae
  • Three letters of reference – at least one must be from a practicing radiation oncologist
  • Dean’s letter
  • Medical school transcript
  • United States Medical Licensing Examination (USMLE) Step 1 and Step 2 (if available) scores
  • A personal statement

We accept and review applicants from students of all accredited medical and osteopathic schools, located within the United States and abroad.

Please note that while we do not have a minimum USMLE score, applicants who match with our program frequently score above 200. We require only Step 1 at the time of application. Do not send additional information to ERAS or directly to us; we only review the above-mentioned documents.

We interview approximately 30 candidates a year and hold interviews in November, December, and January before the year when you would attend. Interviews take a full day (8 am to 4 pm) and include one-on-one meetings with various faculty members and lunch with our current residents. We interview approximately 30 candidates a year and accept two or three PGY-2 positions a year.
