As a social epidemiologist, I deal with health and labour market effects of working conditions among employees. Currently, I deal with occupational risk factors for poor mental health by analyzing BAuA's S-MGA (Study of Mental Health at Work) cohort of workers in Germany. I am also active in the international COPSOQ network and in the Work IPD consortium.. I have worked in monitoring of working conditions and research regarding health effects of work in the Danish Work Environment Cohort Study (DWECS).
