Research Focus

Immunology & Infectious Diseases

Area of Research

Internal medicine/immunology: role of the complement system (especially the lectin pathway) in diseases with significant ischemia/reperfusion damage (e.g. myocardial infarction) and in infections; interventional studies with complement inhibitors in diseases with ischemia/reperfusion damage.

Infectiology: Optimization of antibiotic therapy in hospitals in the sense of "antibiotic stewardship"; optimization of intravenous β lactam therapy by means of concentration measurements and continuous or prolonged infusions.
