Academic Interests

My research is mainly on the passive electrical properties of biological materials (bioimpedance). Since these properties are highly influenced by the anatomy and physiology of the tissue, bioimpedance measurements can be used for characterization or diagnostication of the tissue. It is e.g. possible to use bioimpedance measurements to classify cancerous tissue, to separate between different qualities of meat, to assess the moisture content of the skin or the stress level of a person. These are just a few of numerous possible applications of bioimpedance technology in medicine, biology, sports, cosmetics and psychology. My particular expertise is within bioimpedance basic theory, instrumentation, electrode systems and modeling.


Higher education and employment history

I became an electrical engineer in 1983 and was employed for some years at Siemens AS working with transformer and power stations. I then continued my education at the University of Oslo and became a Cand. Scient. in electronics/instrumentation in 1990.Then Dr. Scient. in 1995 on a thesis on the electrical properties of human skin. Since then I have worked at the Department of Physics, University of Oslo, from 2002 as a full professor. I also have a part time position as researcher at the Department of Clinical and Biomedical Engineering at Oslo University Hospital.
