About me

I was trained to be an oncologist during my medical education, after which I switched my focus to medical research. Since September 2018, I have been working as a PhD student at Karolinska Institutet.

Research description

My research field is cancer epidemiology, especially breast cancer, with a specific focus on the socio-psychological aspect. I am interested in the bi-directional link between psychological stress and cancer risk/prognosis, with an effort to integrate population-based, pharmacological, and omics data.
