Safora Johansen completed her doctorate in radiation oncology and late side effects in breast cancer patients in 2010 at the University of Oslo. As a post doctorate, she continued her research in the same area at the institute for cancer research, Oslo University hospital, Radiumhospitalet. She has participated in implementation of new and advanced radiotherapy techniques, and has studied the effect of these advanced techniques on late side effects development in cancer patients receiving radiotherapy as a part of their treatment. Another research area for Safora Johansen has been about estimating the risk for radiation induced secondary cancer in cancer patients as a result of radiotherapy by employing bio mathematical models. She is now working as a senior researcher at the Oslo University hospital.

She has censorship cooperation with university of Bergen at the faculty of community medicine, college of Bergen and college of Oslo and Akershus at the health department.

Recent interest includes testing the effect of internet support programs for cancer patients and their caregiver.
