The Division of Epidemiology at Mayo Clinic focuses on research related to understanding the occurrence and determinants of states of health and disease in defined populations.

Epidemiology research at Mayo Clinic is centered on patients and other populations to test or generate hypotheses that translate to and from the basic and clinical sciences, with the ultimate goal of improving clinical care for patients.

Within the Division of Epidemiology are numerous ongoing epidemiologic research studies among residents of Olmsted County in Minnesota, Mayo Clinic patients and other populations.

These epidemiologic research studies are intended to advance knowledge about the causes, natural history and outcomes of disease in the community and in Mayo Clinic's practice; to help define population needs; and to help lead discovery in efficacious and cost-effective approaches to delivering specific medical procedures and technologies.
