Quick Facts

  • A varying number of residents are accepted each year depending on the number of positions available
  • 7 total residents are ACGME approved for our training program
  • Graduates are well prepared to work in academic institutions and/or community practices
  • Over 25 departmental faculty members (including Radiation Oncology physicians, Medical Physicists, and Free Radical and Radiation Biologists) train and mentor our radiation oncology residents


  • Residents rotate several times with each physician faculty in specialized clinics ensuring that the breadth and depth of each disease site is covered
  • Research rotations in the first and second year give residents dedicated time and resources to actively engage in research and produce/submit abstracts and manuscripts
  • Pathways (16 weeks) allow for PGY4-5 residents to individualize their residency education and specialize in areas of interest within the field.


What procedures do you do in your clinic?

  • Image of stererotactic radiosurgery setupWe have incredibly strong physics support, which allows us to do a wide variety of special procedures. This list is probably incomplete, but here are some: low dose rate brachytherapy for prostate cancer, high dose rate brachytherapy for gynecologic cancers, intraoperative radiation therapy for breast cancer, stereotactic radiosurgery for intracranial lesions, frameless stereotactic radiotherapy, stereotactic body radiosurgery for liver and lung tumors, gated treatment delivery, conebeam CT for tumor localization, total body radiation therapy, and total skin radiation therapy.

Is there sufficient patient volume so that I can have multiple exposures to a variety of conditions?

  • One of the strengths of our residency program is that we see a wide variety of cases. We are fortunate to work in an excellent hospital with strong programs in multiple disciplines, such as Otolaryngology, Neurosurgery, and Medical Oncology to name a few. These departments see patients from all over Eastern Iowa, and those patients are then subsequently referred to our department for radiation therapy. We typically have 60 – 90 patients under treatment at any time.

Do I have to rotate outside UI Hospitals & Clinics to fulfill requirements?

  • There are enough brachytherapy and pediatric cases to fulfill requirements for board certification. If residents are interested in additional experience in these areas, outside rotations can be arranged.

What's the call schedule like?

  • Residents take call several times throughout the year for 1 week. Occasionally, residents are needed to cover the clinic briefly on Saturday or Sunday mornings. Rarely, residents are called during the night to emergently treat a patient.

Do you have a research project requirement for graduation?

  • Yes. Not only do we have a research project requirement, but we have a research curriculum in the first two years of residency that helps strengthen and promote research skills while giving residents dedicated time to focus on their projects. Our residents have been very successful and productive in their research efforts and have all been accepted to present a poster at our national specialty conference, ASTRO. Additionally, residents can choose a research pathway in their last two years if interested. See what research our residents are working on.

Are residents involved in any clinical trials/protocols?

  • Image of ascorbate clinical trialWe encourage all residents to be involved in clinical trials. We try to tailor residency to a particular resident’s individual needs and interests. Residents who are interested in a career in academic Radiation Oncology will likely opt for our Research or Holman Pathways. Other residents interested in private practice will also have ongoing research projects, but will focus more on developing their expertise on our Clinical Pathway.

4-Year Educational Plan

Scoping patientIn order to train future practitioners of radiation oncology, we provide a comprehensive educational experience that will expose residents to all aspects of radiation oncology. We have designed a curriculum that is innovative, individualized and integrative. The residency experience entails clinical rotations, didactics (graduate level courses and several weekly conferences and tumor boards) dedicated research time, and pathways that allow residents to specialize and focus on areas of interest within the specialty. Residents finish the program with a deep understanding of cancer including the biology, pathology, natural history, work-up and treatment approaches with radiation therapy, surgery and chemotherapy. Residents become competent in the delivery of radiation therapy including techniques of external beam radiotherapy as well as interstitial and intracavitary radiotherapy. Through a variety of experiences and resources available, residents become well prepared for their board examinations.

Clinical Rotations

Radiation Oncology Clinical Service

In order to obtain the essential skills and knowledge, residents will spend a significant portion of their residency on the Radiation Oncology Clinical Services. Each physician faculty runs their own clinical service specializing in specific disease sites. Residents will rotate through each service at least three times throughout residency and potentially more if interested in a specific service/disease. Clinical rotations will vary in length each training year in order to meet the overall educational learning goals.

Department faculty clinical services include:

Faculty Clinical Service Topics/Disease Sites Special Procedures
Carryn Anderson, MD Head and Neck, Melanoma, Sarcoma, Skin/Soft Tissues Eye Plaque Brachytherapy, Spinal Stereotactic Radiosurgery

Research is a vital component of the residency program. A curriculum has been established to hone resident research skills and knowledge with ample research opportunities and resources while providing residents with dedicated, protected time for their clinical research. The department has a research team that serves as mentors and resources for residents. Protected research time is tailored to resident needs and interests and is most often arranged during PGY3-PGY5. Every resident is expected to have submitted a manuscript for publication by the end of residency.

Petri dishResident Research

Residents in our department have been very productive and successful with their research endeavors. Each resident has one or more abstract acceptances to national conferences and many have manuscript submissions.

Resident Research Showcase

We are very proud of our resident research efforts, and want to showcase their projects! The Annual Resident Research Showcase is held during the annual ISTRO meeting. This allows residents to present their posters to meeting participants while also giving them experience and feedback on their presentation and poster before they present at ASTRO.

PGY4-5 Research Opportunities

Some residents choose to continue their research endeavors more in-depth. Residents can select to do a Clinical Research Pathway or apply for the Holman Pathway for those who want a career as a physician investigator and are interested in basic science, clinical or translational research.


“The beauty of our clinical pathways, whether it be academics, research, or community medicine, is that they allow us to be well-rounded, competent clinicians while providing us the autonomy and initiative to fashion our unique niches in health care (medical education, innovation, public policy, global health, clinical trial initiation, etc.)."
-Sagar C. Patel, MD

In order to help residents meet the learning goal of focusing and specializing in areas of interest, residents will choose and/or develop a Pathway by mid-residency. Pathways are individualized learning experiences developed around specific areas that correlate to each resident’s personal career goals and interests. Approximately 16 weeks of residency will be devoted to a selected Pathway to be taken in PGY4 and PGY5. Currently, developed Pathways include, but certainly are not limited to:

  • Clinical Research - Residents who develop a keen interest in clinical research after the first two years can continue their projects and further develop their skills
  • Academic Medicine - Residents interested in pursuing an academic career i.e., in medical education, public health, etc. can work simultaneously on their Masters degrees in Medical Education or Public Health during residency.
  • Clinical Medicine - Residents who want to focus more on their clinical skills and practice can choose the Clinical Medicine Pathway. Learning experiences will encompass more exposure and experience for specific procedures or disease sites and a variety of clinical Radiation Oncology experiences (i.e. community medicine rotations)

The Holman Pathway

“The Holman Pathway afforded me protected time to really focus on basic science research and provided me a foundation for a successful academic career as a physician-scientist.” 
–Darrion Mitchell, MD, PhD

The Holman Pathway presents an alternative residency structure for selected residents in Radiation Oncology. It’s a special training program available for residents who are planning a career in basic science or clinical research. Residents become eligible for board certification after 21 months of research and 27 months of clinical training.

Holman Pathway residents are required to meet the same minimum requirements for special procedures (interstitial and intracaviatry brachtherapy and unsealed sources) as well as pediatric cases. HP residents are not required to take the curriculum selectives (Radiology, Physics, and Dosimetry and the PGY3 Research Curriculum). Additionally, the clinical rotations will be designed to meet the HP resident needs.

Learn more about the Holman Pathway.

Independent Study and Board Preparation

Resident on computerThe field of Radiation Oncology is a highly academic specialty in which residents need to continually and consistently on their own, study the vast amount of content. For successful completion of the residency program, passing boards and effectively integrating knowledge into patient care – it is expected that each resident begins this independent study process from day one of residency. Residents will develop their own Learning Plan each year and will be monitored for progress by the Program Director semi-annually.

In addition to independent study, the program offers several exams annually to help prepare residents for boards. Residents are required to take and perform at an expected level for the following exams: In-Service, RAPHEX (physics), and Mock Orals. In-Service and RAPHEX exam scores allow residents to compare and gauge their performance nationally against their peers. The goal of mock oral exams is to simulate the actual board exam so residents are not only prepared for the medical knowledge but for the test-taking skill itself. Residents also have the opportunity to take the RABEX (radiation biology).


Both conferences and courses are offered on a continual basis that residents are required to attend in order to be exposed to the full spectrum of content in Radiation Oncology.

Residents have the opportunity to learn from faculty, guest speakers, and peers in a myriad of venues, including several departmental as well as interdisciplinary conferences and tumor boards on a weekly basis. Residents also develop excellent presentation and speaking skills by frequently giving lectures and honing their teaching efforts.

Clinical Case Conferences

Twice a week, residents and faculty present Case Conferences that pertain to specified disease sites and relevant patient cases. Residents present ½ hour, concise power point presentations on a disease site, while faculty facilitate discussion and present patient cases to engage all learners in this interactive learning session. Both residents and faculty come prepared to teach and learn! Topics are presented in a longitudinal curricular approach so residents are exposed to all topics throughout the year rather than one month at a time.

The following elements are included in each Case Conference pertaining to the disease site:

  1. Work up, diagnosis and staging of the patient’s case
  2. Treatment options
  3. Particular radiation plan used to treat the patient
  4. Review of relevant sentinel studies or literature supporting the use of radiation for the patient
  5. Potential acute and long-term complications of the treatment
  6. Prognosis and other expected outcomes
  7. Relevant patient cases

Chart Rounds

Chart Rounds occur once a week and focus on our clinic patients starting treatment. Residents briefly present the patient’s diagnosis, stage, brief history, and a description of the treatment plan. Input is provided from faculty, physicists, dosimetrists, and staff.

Residents become very familiar with the patient’s treatment plan by displaying and describing relevant treatment fields and dosimetry, understanding how the GTVs, CTVs, and PTVs were constructed, and awareness of the goal doses to each PTV along with the doses to each dose-limiting structure.

Journal Club

Journal Club meets at least six times a year to focus on Practice-Based Learning and Improvement skills. The curriculum prepares residents to effectively investigate and evaluate their patient care practices, and appraise/ assimilate scientific evidence by utilizing an Evidence Based Medicine approach. Residents will increase their EBM skills, effectively be able to facilitate a Journal Club discussion and ultimately apply their knowledge to improve their own patient care.

Tumor Boards

Residents are required to attend specific disease-site Tumor Boards. Medical and allied professionals from a variety of departments attend tumor board conferences and focus on the interdisciplinary nature of patient care. The following Tumor Boards are scheduled 2-4 times a month.

  • Melanoma
  • Thoracic
  • Sarcoma
  • Lymphoma
  • Gyn Onc
  • Peds Onc
  • Neuro-Path
  • Genitourinary
  • Head and Neck
  • Breast
  • Hepatic

Personal and Professional Development Series

To help residents grow personally, professionally, and healthfully, the Department offers this series to cover a variety of issues relevant to a resident’s life, practice and health. Residents meet with a variety of in-house guest speakers and discuss topics listed below. Additionally, every other year the department sponsors a Resident Retreat that focuses on resident wellness, team building and special topic issues.

  • Giving Bad News
  • Nursing Topics
  • Impaired Residents/Faculty
  • Billing and Coding
  • Teaching Skills 
  • Cultural Diversity

It is the goal of the Department of Radiation Oncology at the University of Iowa to produce quality radiation oncologists who pursue either an academic or private practice career. To do this, we feel that it is necessary to choose high quality residents from the pool of applicants each year. Future residents are selected based on academic achievement, personal qualities, and the faculty's assessment of their potential to excel in the residency program. In general, most successful applicants are in the top third of their medical school class and graduate from LCGME schools that provide superior undergraduate medical education.

Our People

Our department is patient centered and the attitude shared by staff reflects this. Faculty compose a good blend of clinical and research skill sets with a broad knowledge of all the treatment modalities, yet with a profound depth of knowledge in their specialty area.

Many of the clinical-track graduating physicians begin careers in private practice with the balance entering academic medicine.

Each of our Faculty members is board certified in Radiation Therapy and accredited. Owing to the interdisciplinary nature of Radiation Therapy many share joint appointments in other disciplines.
