I am an epidemiologist who is interested mainly in determinants of cancer occurrence and progression. My work, primarily in prostate cancer, focuses on markers of psychological stress, infection, and inflammation – alone and in combination. Ongoing projects include studies of factors that may alter the influence of stress on cancer progression, including individual stress susceptibility and medical treatments. Psychological stress is measured on many levels, from questionnaire data and register-based assessment of stressful life-events, to altered signaling in stress-related molecular pathways. The studies use epidemiological study designs and are mainly based on cohort and register-based data.
