Research Opportunities

A Mayo Clinic radiation oncology faculty member inspects radiotherapy equipment.

The department is dedicated to the training, development, and mentorship of the next generation of impact researchers in medical physics. Many of our faculty serve in leadership roles on internal, national, and international societies.

Research training is integrated into the three-year program and coordinated with your clinical training. Research projects are directly related to clinical applications of physics in the practice of radiation oncology. During your residency, you will have a primary research project and opportunities to be involved in smaller research projects, all with potential for a publication.

Before you start the residency, you will have an opportunity to review proposed research projects for your primary project. Your areas of expertise and your areas of interest will help identify a good match for a project; we want every resident to be motivated and involved in a research project they are interested in.

All residents are expected to produce publishable work during their residency. A wide variety of support systems for research exist including research coordinators, internal funding opportunities, biostatisticians, editorial services, and media support services.

In addition, Mayo Clinic provides trip days and expense reimbursement for presentations and abstracts accepted at regional, national, and international meetings.
