The group has activities within several research areas within biomedical optics. Most projects are run in close cooperation with other research communities, i.e. the biomechanics group at the department of structural engineering at NTNU, and researchers at the medical faculty and St. Olavs hospital. The group is an important part of Network for Biomedical optics, which is part of the Strategic Area of Medical Technology at NTNU. The most important areas of activity are
- Tissue characterization and optical diagnostics
- Optical dosimetry
- Forensic medical optics
- Characterization of plaques in the coronary arteries
- Photodynamic therapy
Laboratory facilities
Biomedical optics is an area with much laboratory activity, for information regarding laboratory facilities see laboratory facilities.

The main goal of this project is to develop an objective, accurate method to characterize and date bruises in forensic science.
Determining the age of injuries on a victim's body is an important aspect of forensic medicine, for example in cases of abuse. Visual assessment is most commonly used to estimate the age of a bruise. However, interpretation of the finding is purely subjective and relies strongly on the skills and experience of the observer, and might be disturbed by factors like e.g. ambient lighting or photo quality. The uncertainty in the result is therefore comparatively large. Thus, there is a need for an objective, easily manageable method to date bruises. This study has been initiated to develop such a method based on optical methods for tissue diagnostics, e.g. reflectance spectroscopy or hyperspectral imaging, combined with mathematical models developed to describe the temporal development of a bruise. To construct such a method it is important to have a thorough knowledge about how human tissue responds to a traumatic incident. This study is of an interdisciplinary nature and requires a combined effort from electrical engineering, physics, biomechanics, medicine and forensic science. See also the list of publications .

Atherosclerotic plaque created in the coronary arteries may limit the blood supply of the heart muscle, and in the worst case may lead to sudden death. Optical spectroscopy is a promising method to find and classify these plaques such that suitable treatment can be given. In this project, spectroscopy is being used to survey and classify plaque both by way of optical fibers and hyperspectral imaging.
