I am involved in teaching clinical neurology to 5th year medical students at the Department of Neurology, where I also served as Clinical Amanuensis in 2013.

Since 2015, I am involved in the oral Integrated Preparatory Examination taken by medical students after two years of study, assessing their ability to integrate and apply knowledge of the medical sciences prior to entering the clinical phase of medical education.

In 2016-2020, I was elected to the European Stroke Organisation Educational Committee, working with the World Stroke Academy, a collaborative educational project between the World Stroke Organisation and the European Stroke Organisation. It can be found at https://world-stroke-academy.org/

In 2011, I set up a Swedish translation of the patient information website www.neurosymptoms.org on functional and dissociative neurological symptoms, originally created by Dr. Jon Stone in Edinburgh. The Swedish site can be found at http://www.funktionellasymptom.se and has since its inception been viewed over 800.000 times.
