Tarjei Widding-Havneraas
PhD candidate in Epidemiology, University of Bergen
PhD candidate in Epidemiology, University of Bergen
I am a PhD candidate in Epidemiology at the Department of Clinical Medicine, University of Bergen, Norway and the Competence Centre for Research and Education in Forensic Psychiatry, Haukeland University Hospital. I am also a researcher at the University of Oslo, working with inequality in education in the EQOP-project.
In 2021-2022, I had the privilege of working with Felix Elwert as an Honorary Fellow at University of Wisconsin-Madison, USA. During my stay we worked on quasi-experimental designs with Norwegian administrative data. My PhD has included training in epidemiology and causal inference from London School of Hygiene and Tropical Medicine and University of Essex.
I hold an MPhil in Sociology and a BA in Economics from the University of Bergen. In my spare time, I enjoy basketball, art, and books.
PhD project: Effect of ADHD medication on criminality and injuries
My PhD examines the effect of ADHD medication on criminality and injuries using preference-based instrumental variables and the extent to which ADHD symptoms, diagnosis, and medication vary geographically.
