Research

Main fields of my research are within epidemiology related to cardiac
surgery. Together with a number of co-workers we have published reports of
topics such as age and obesity related risks, diabetes, repeat cardiac
surgery, infections, endocarditis, bleeding and neurologic complications,
perioperative myocardial damage, late cardiac tamponade and on the effect of
cardio-pulmonary bypass.
