I am professor at the Institute of Community Medicine, University Medicine of Greifswald and within this institute deputy head of the Department of SHIP/ Clinical-Epidemiological Research. I lead the functional division “Quality in the Health Sciences”. My research focuses on methods and research quality related projects. This comprises for example developments related to metadata standards, quality management procedures, data quality tools and other research infrastructures. As to study design, I foremost deal with population based observational health studies. My projects also relate to the data linkage of primary and secondary data including registries, claims data, and hospitals. Research topics beyond methods comprise the study of subclinical and clinical disorders, particularly musculoskeletal disorders, and incidental findings.
