Focus of research:

The focus of research is twofold. On the one hand, I am interessted in the epidemiology of potential traumatic events and posttraumatic stress disorder and the life-long consequences for people in terms of quality of life, physical conditions and mortality. On the other hand, research is focused on identifying potential biomarkers for posttraumatic stress disorder. More specifically, consequences of chronic stress on alterations in the stress hormones, cholesterol, homcysteine metabolism, antioxidants, fatty acids, but including immunology as wel.
