Eva Onjukka

Eva Onjukka is a Medical Physicist and R&D Coordinator for external-beam radiotherapy physics at Karolinska University Hospital. She is affiliated with the Department of Oncology-Pathology at Karolinska Institutet and part of Åsa Carlsson Tedgren's Clinical Radiation Therapy research group.

• PhD in Medical Physics (University of Liverpool, 2011)
• Docent in Oncology (Karolinska Institutet, 2024)

Her research focuses on radiobiological modeling and optimization of radiotherapy treatment plans, particularly in head and neck cancer and Stereotactic Body Radiotherapy (SBRT). She works extensively with real-world data from electronic quality registries to develop dose-response models for acute and late radiotherapy side effects.

Recent publications highlight trends in SBRT dose optimization for lung tumors, reirradiation safety, and predictive modeling for xerostomia and dysphagia. Collaborative studies span multiple cancer types (prostate, esophageal, sarcoma) and emphasize integrating machine learning with clinical data.

• Scientific Awards: Fellowship from the Swedish Cancer Society

She supervises research projects including 1 completed PhD, 2 ongoing PhDs, and 7 completed Master’s projects. Her work is supported by grants from Varian Medical Systems and Cancer Research Funds of Radiumhemmet.

Active in European Society for Radiotherapy and Oncology (ESTRO), she contributes to national guidelines for organ-at-risk delineation and automated radiation therapy data collection. The research environment includes interdisciplinary teams of physicists, oncologists, and nurses focused on improving patient outcomes through evidence-based treatment planning.
