Björn holds a Degree of Master of Medical Science with a Major in Psychology from Karolinska Institutet, where he wrote his thesis while working as a research assistant at Harvard Medical School in the US. Before retraining as a psychologist, he worked as a journalist for Dagens Nyheter and served in both editorial and executive management positions. His curiosity and fascination with people have been the driving force in both his career as a journalist and as a psychologist.
In his work with people, Björn focuses on relationships, communication, and the kind of actionable life hacks that have made ‘Dumma människor’ so appreciated. From leadership and sleep to professional life and romantic relationships, he unpacks common everyday challenges and offers practical advice to make life a little easier.

In 2023, Björn published ‘Omtyckta människor – Forskningen, knepen och övningarna som gör dig likeable’ (‘Likable People – The Research, Tricks, and Exercises That Make You Likeable’, Polaris). In the book, Björn dives deep into the fascinating science behind what makes us likeable.
