My on-going project is about improving performance and safety of clinical biomaterials.
Bergen retrieval center for implants is collecting and analyzing joint prostheses that have failed due to aseptic loosening, often in combination with osteolysis or other immunological reactions.
I have specialised in trace element analysis, mainly on clinically related samples. Main elements of interest are Co, Cr, Zr, Mo, Ni and Ti measured by ICP-MS.

Bergen Implant Retrieval center for Implants
The overall goal of our projects is to improve the performance and safety of orthopaedic and other surgical implants by a clinic-laboratory interaction.
Clinical performance of artificial materials can be predicted and improved by investigation of the retrieved devices that have been in clinical use, by a translational research approach, addressing biocompatibility and assessment of physical behavior.
