I feel a bit awkward presenting my CV, but I believe it is important to share my academic achievements. I believe it is important for young researchers considering my advice to understand that it is grounded in my own successful experiences. By presenting my accolades, I hope to provide reassurance that the guidance I offer has been effective in my journey as a researcher.
Career summary
I started my career as a researcher in 2018 when I began my PhD on group CBT for youth with anxiety. I have continued my work and after finishing my PhD in 2022, I got a tenured position as a researcher where I work 80% doing research on treatments for youth mental health. Furthermore, I also work 20% as a statistician supporting all researchers at the Hospital of Southern Norway.
