About me

Currently, I am a Doctoral Candidate in Clinical Epidemiology (PhD) at the Centre for Translational Microbiome Research at Karolinska Institutet in Stockholm. I received my main clinical training in Finland, most of my academic training in Sweden and I have gained a broad knowledge and understanding of clinical epidemiology, and a passion for women’s health.

 

My goal is to better understand the association of commonly prescribed drugs with cancer development. In specific, my research is focused on contemporary use of menopausal hormone therapy (MHT) and antibiotics on the risk of particularly sex hormone related cancers.

Research description

Most of my projects are based on large, nationwide and population-based databases. Data is linked to several National Board of Health and Welfare supervised health data registries, such as the Swedish Prescribed Drug Registry, Patient Registry (in- and outpatient care), Swedish Cancer Registry and Causes of Death Registry.
