About me
I focus on adolescent psychiatry, specifically employing causal symptom networks generated from respondent perceptions. The traditional view of psychiatry assumes that a diagnosis such as depression is a distinct entity, which runs into problems with comorbidity and huge heterogeneity within the categories. An alternative, the network approach, instead shifts focus to the levels of the symptoms, and how one symptom may influence other symptoms. These influences (or rather, some of them) are assumed to be highly individual. This can be visualized as networks and used, among other things, to simulate effects of different treatment targets, and thus enable individualized interventions.
An example:

I hope to be part in the future transformation of psychiatric taxonomy, in which we move towards a more dynamic and nuanced understanding that can better capture the complexities of individuals, while sticking to quantifiable and systematic methods. If you want to try out the methods, links are at the bottom of this page.
My background is in behavioral interventions for children with autism, which of course remains an interest :)
Also, I write childrens books!
