From the senior residents
Welcome, and thank you for your interest in the Clinical Medical Physics Residency program at Mayo Clinic, Rochester, Minnesota. As senior residents, we are proud to share with you what makes this program an exceptional place to begin your career. Over the past two years, we have grown not only as clinical physicists but also as contributors to research and innovation in the field. This has been made possible by the unique strengths of our program.
One of the most defining aspects of our residency is the size and accessibility of our faculty. With a large team of experienced physicists representing a broad range of specialties, we benefit from consistent mentorship and diverse perspectives across every rotation. Whether we need guidance on patient care, designing a research project, or preparing for board exams, there is always someone ready to help.
Our clinical training has been immersive from day one. We’ve been actively involved in patient care, from treatment planning and chart checks to introducing new technologies into the clinic. Residents are supported through a credentialing process that enables us to cover clinical operations and build our competence. This level of responsibility and trust has prepared us to feel confident in transitioning to independent practice.
Perhaps most exciting is the breadth of technology available to us. From adaptive radiotherapy and proton therapy to spatially fractionated techniques, the variety of platforms and modalities we’ve trained on has given us a well-rounded and forward-looking foundation.
However, the hallmark of our program is its strong research culture. The quality of the research available is a major factor defining a three-year residency. We’ve had the opportunity to contribute to projects with real clinical value, present at national and international conferences, and publish our work. Importantly, our research extends beyond publications. Our research mentors actively provide guidance such that we can translate our work to the clinic before graduation.
We are grateful to have trained in a program that emphasizes clinical excellence while encouraging curiosity, collaboration, and innovation. If you are seeking a residency that offers comprehensive training, a vibrant academic environment, and exposure to some of the most advanced technologies in radiation oncology, we believe you will find it here.
We wish you the best in your search and hope to welcome you into our program soon.
Kind regards,
Darwin Garcia, Ph.D., Brandon Reber, Ph.D. and Ruiming Edmondson, Ph.D., M.S.
