What I Do All Day
Writing Grant Requests

Fund raising eats up a large amount of my time. ion-cash

Data Wrangling

Preparing data for statistical analysis is fun, but always takes more time than expected.

Writing Papers

I spend not enough time writing papers.


I try to help others in planing clinical studies and in data wraning and statistical analysis.


I teach mainly scientific methods, but also clinical reasoning, pain related stuff, and exercise for people with health problems. I teach mainly physiotherapists, but also some courses to other health professionals.

Fun Facts
I own four guitars but only know three chords
I won CHF 10 prize money as a cyclist (it was a rainy day in the mountains and most of the others gave up)
I have an expensive espresso coffee machine but prefer thin filter coffee
No driving licence
