I am  a professor of clinical neurosurgery, Faculty of Medicine, University of Oslo, senior consultant neurosurgeon/section chief at Department of neurosurgery, Oslo University Hospital – Rikshospitalet, and group leader of The Neurovascular-Hydrocephalus Research Group, Oslo University Hospital, Oslo, Norway.

I have extensive experience from various fields of neurosurgery; my special fields of interest and current clinical activity include: Cerebrovascular surgery (cerebral aneurysms, cerebal vascular malformations), microvascular decompressions (trigeminal neuralgia, hemifacial spasms, glossopharyngeal neuralgia, vertigo), shunt/endoscopic surgery for hydrocephalus and other cerebrospinal fluid (CSF) circulation disorders (normal pressure hydrocephalus, dementia, idiopathic intracranial hypertension, non-communicating hydrocephalus), and surgery for brain tumors (posterior scull base, ventricular).

The goal of my research is to improve neurosurgical practice by (1) enhancing knowledge about the pathophysiology of neurosurgical/neurological diseases, and (2) developing new methodology for physiological monitoring of neurosurgical/neurological conditions. My major present research activities are studies on non-invasive ICP monitoring, development of methodology for analysis of intracranial pressure (ICP), arterial blood pressure (ABP) and cerebral auto-regulation, and studies on the pathophysiology of hydrocephalus and other disorders of CSF/brain water circulation.

I have been involved in research-based innovation and was in 2001 a founder of the company dPCom A/S (former Sensometrics A/S), which is a manufacturer of medical equipment (software and hardware) for digital processing and analysis of pressures.
