National Hospital for Neurology and Neurosurgery

Autonomic Unit

Professional background

I am a Consultant Neurologist in the Autonomic Unit at the National Hospital for Neurology and Neurosurgery.  I studied Medicine at the University of Oslo, Norway, and did my specialist training in Neurology at Haukeland University Hospital, Bergen, Norway.

During my specialization I completed my PhD Thesis: “Traumatic spinal cord injuries – A clinical and epidemiological study” at the University of Bergen, Norway.  I was a Visiting Research Fellow for 14 months, at both UCLH and Imperial College London, as a postdoc funded by the University of Bergen, Norway.   I was awarded the Investigator Award 2012 Autonomic nervous system disorders at the Congress of the European Federation for Neurological Societies.

During this period I was headhunted to Denmark where I worked as an Associated Professor at Aarhus University and as a Consultant Neurologist in Spinal Cord Medicine at the Spinal Cord Injury Centre of Western Denmark, Department of Neurology, Regional Hospital of Viborg where I built an Autonomic Lab and developed a research unit at the Spinal Cord Injury Centre of Western Denmark.  I was also a part of the multidisiplinary management team leading the Spinal Cord Unit.

I have a strong interest in Autonomic Neurology, Spinal Cord Injuries and epidemiology.  I run specialist Autonomic Neurology Clinics at NHNN and participate in the specialist Autonomic Neurology Service at NHNN along with my colleagues, Dr Ingle and Dr Iodice. 

I also have an interest in electronic health record systems (EHRS) and diagnostic coding.  I have experience of different EHRS and the implementation of new systems in both Norway and Denmark.  I led the development of a Spinal Cord Injury Database which communicates with the electronic health record at the Spinal Cord Injury Centre of Western Denmark and IT Central Denmark Region, Aarhus, Denmark.  We also developed our web pages and patient leaflets.

I am a co-supervisor for a PhD student in Denmark studying spinal cord injuries and neuropathic pain.
