Professor Olav Rooyackers

Professor of Experimental Anaesthesiology and Intensive Care Clintec, Karolinska Institutet and University Hospital, Huddinge, Sweden

Prof Rooyackers received his PhD from the University of Maastricht in 1995, after which he held post doctoral positions at the Mayo Clinic and Foundation in Rochester, USA and at the University of Edinburgh, Scotland. He has been with his current research group at Clintec, Karolinska Institutet and University Hospital, Huddinge, Sweden for 16 years.

The research group is dedicated to the nutritional and metabolic problems of critically ill patients treated in the Intensive Care Unit. One of the focus points is the dramatic loss of muscle mass that these patient experience and that negatively affects their survival and recovery. We are investigating the causes for the loss and the possibilities to influence this by nutrition.
