Why I Chose Oxford’s MSc in Medical Physics with Radiobiology—and Where It Took Me

The MSc in Medical Physics with Radiobiology at the University of Oxford’s Department of Oncology welcomes students looking to kickstart a career in medical physics research, clinical practice, or related industry positions. The one-year, full time programme covers a broad range of topics, including the underpinning physics of radiation action, how ionising and non-ionising radiation are used in clinical practice, and research approaches in the field of medical physics. With its additional focus on the principles of radiobiology at a molecular and cellular level, students gain a thorough grounding in the biological effects of radiation.

Dunja Stojanovic studied the MSc in Medical Physics with Radiobiology in 2023, having been awarded a scholarship through the prestigious IAEA Marie Skłodowska-Curie Fellowship Programme. It helped her to deepen her scientific knowledge, develop advanced research skills, and build confidence in her career path. Dunja is now undertaking an internship with the International Atomic Energy Agency (IAEA), specialising in dosimetry and medical radiation physics. 

Can you tell us about your background?

As a child, I dreamed of becoming a doctor. However, as I grew older, I discovered an aptitude for math and physics, which sparked my curiosity and led me to pursue a degree in applied physics. During my undergraduate studies at the Faculty of Physics, University of Belgrade, I was introduced to medical physics: a field that applies radiation physics to healthcare, directly impacting patient diagnosis and treatment. This discovery felt like a true calling, and I knew that pursuing a master’s degree in medical physics was going to be the next step in my journey.

How did you hear about the MSc in Medical Physics with Radiobiology course and what made you decide to apply?

As I explored universities offering MSc programs in medical physics, I came across the open applications for this course. Its emphasis on clinical aspects, combined with radiobiology, struck me as a unique learning opportunity for someone with a physics background. Like many who are passionate about knowledge, studying at Oxford felt like a dream. Encouraged by the support of my undergraduate lecturers, I decided to apply.

After receiving my offer, I applied for the prestigious IAEA Marie Skłodowska-Curie Fellowship Programme (MSCFP), which supports women pursuing master’s studies in the nuclear field. Beyond the financial assistance that helped cover my tuition fees, the program also offers internship opportunities after graduation. However, being awarded the MSCFP meant much more to me—it gave me a profound sense of purpose and encouragement. Receiving a fellowship honoring a pioneering woman in nuclear science connected me to the legacy of women who have made a significant impact on the field and reinforced my commitment to advancing nuclear science in medical applications.

What did you enjoy most about the course?

What I enjoyed the most about the course was its combination of lectures and scientific research. The eight taught modules provided essential knowledge across various clinical applications of physics, covering everything from the fundamental radiobiology of cells and tissues to radiation safety, ionising and non-ionising imaging modalities, and radiotherapy. After building a strong foundation through coursework and exams, I had the opportunity to choose a research project based on my interests and work under the guidance of inspiring supervisors, making the experience particularly exciting. I appreciated how this structure continuously built upon my knowledge, broadening my perspective and sparking new ideas.

What were your next career steps after completing the MSc in Medical Physics with Radiobiology?

After completing my MSc degree, I accepted an offer for a one-year internship at the Dosimetry and Medical Radiation Physics Section of the International Atomic Energy Agency (IAEA), where I am currently working. In this role, I support the IAEA/WHO Secondary Standards Dosimetry Laboratory (SSDL) network activities, allowing me to apply the knowledge and skills I developed during my master's studies. This experience has provided me with a comprehensive understanding of calibrations, international dosimetry codes of practice and their implementation.

Given the rapidly evolving nature of medical physics and its applications, it is difficult to predict exactly where my path will lead, but I am confident that research will be a fundamental part of it. 

How has the MSc in Medical Physics with Radiobiology helped you to achieve your career goals?

The knowledge I gained from the course, along with the support of the MSCFP fellowship, has been instrumental in both my professional and personal growth and has laid a strong foundation for my future endeavours.

Engaging in my MSc project was my first experience with transdisciplinary research, strengthening my ability to critically analyse data and interpret complex results within a clinical context. Working at the IAEA further deepened my understanding of the importance of accuracy, consistency, and traceability in dosimetry measurements for ensuring patient safety.

Beyond technical skills, this journey also taught me to believe in myself and my work. The unwavering support from the MSc course team, my supervisor, and the Marie Skłodowska-Curie Fellowship Programme gave me the confidence to push my limits, recognise my worth, embrace challenges, and strive for excellence— all of which I am deeply grateful for. 

What is your top tip for students wanting to study here?
