My research focuses on how perceptions of the social world affect well-being and on developing interventions when this perception causes problems. I study this using both clinical trials and experimental paradigms. 

The social world and mental health 

The social world and how it is perceived is of great importance for understanding many mental health problems

My research focuses on understanding the role of the social world in mental health. My primary research interest is in understanding the phenomenon of loneliness and why it becomes a lasting problem for some people. For my Ph.D. I investigated whether internet-based psychological treatments can be of help for this group. The SOLUS intervention that we have developed has now been used successfully in different iterations both in Sweden and abroad.

Additionally, I have recently served as the lead in an experimental study studying how morphine affects social cognition. Understanding the neurobiological basis and mechanisms of such processes can hopefully help gain a broader understanding of how perceptions of the social world ties into mental health in general and substance use disorders in particular.

I am currently also involved in two studies on psilocybin-assisted psychotherapy. The first of these (led by Dr. Rebecca Böhme) targets complicated grief, while the second (led by Dr. Leah Mayo) focuses on treating social anxiety in people who have not been helped by other treatment options.
