Affiliated Researcher, Docent

My research

My research area is medical radiation physics where I work in the fields of radiation dosimetry and radiation therapy with a special focus on various aspects of brachytherapy.

Brachytherapy is a form of radiation therapy for cancer where small sources of ionizing radiation are used to irradiate tumours from within the patient.

I currently hold a Senior Clinical Investigator Award from the Swedish Cancer Society providing 70% research time 2018-2024. I combine my research here at LiU with clinical work as a medical physicist in radiation therapy at the Karolinska University hospital. I am connected to the Centre for Medical Image Visualization, CMIV, here at Linköping University and have an affiliation to the Department of Oncology-Pathology at the Karolinska Institute.

Research

Quantitative computed tomography for more accurate radiotherapy

We are developing quantitative image reconstruction methods with dual-energy computed tomography to measure the atomic composition of patient organs before radio therapy.

Organisation

Department of Health, Medicine and Caring Sciences (HMV)

The research areas at HMV include experimental basic research to clinical, social and public health research. We conduct high-quality education in the sought-after care professions.
