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 on the EQOP-project at University of Oslo.
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 BSc in Economics from the University of Bergen. In my spare time, I enjoy basketball, art, and books.
PhD project: Effects of ADHD medication on injury and crime prevention
My PhD examines (i) the use of variation in medical practice patterns as instrumental variables, (ii) the extent to which ADHD symptoms, diagnosis, and medication vary geographically, and (iii) effects of ADHD medication on injuries and crime.
