    3. "Motor neurons – can they be counted?" Clinical study on a new biomarker for ALS 2019-
    4. "Digital gold mining in historical neurophysiological datas" – National quality study 2020- .
    5. Local PI for the "Puccini" clinical RCT study–BAY1878080 in the treatment of diabetic neuropathic pain. 2020–
    6. Responsible for development and maintenance of "Neuroscience registry for research and quality studies" for Oslo University Hospital 2014 –.
  • He collaborates with several projects in neurology, oncology and ortophedics.  Some of these are listed in his Cristin profile. He also participates in several international projects like the EU Horizon 2020 funded project Dolorisk, and a large international multicenter study investigating the validity of the neurophysiological MScanfit MUNE technique. 

    Supervising experience

    Methodology and interests
    His research is focused on clinical neurophysiological methods and pain mechanisms. He is currently leading projects focusing on mechanisms and treatment of neuropathic pain and carpal tunnel syndrome. His interests also includes methodological studies of clinical neurophysiological methods and human pain models. He is also involved in studies of narcolepsy, migraine, sleep disorders, pain genetics, side effects of cancer treatment, as well as studies on health effects of shift work. He has published more than 80 peer-reviewed papers, with a Google Scholar H index above 25. In his clinical work he is involved in the clinical investigation of patients with various neurological diseases, including epilepsy, neuromuscular disorders and all kinds of neuropathies.
