Research description

My research interests focus mainly on epidemiology and etiology of cancers of the aero- and digestive tract, and recently extend also to neurodegenerative diseases.

Research activities consist of register-based research, large-scale field work in different parts of the world, as well as setup of a molecular biology laboratory dedicated to molecular epidemiology (microbiome, tumour mutation, etc).

I have trained 10 doctoral students and most of them have been promoted as independent group leaders. The research group currently consists of 6 postdocs/junior staff and 6 doctoral students, as well as visiting researchers/students and master students.

So far I have published 210 peer-reviewed research articles with more than 5000 citations.
