Summary At Henry Ford, epidemiologists lead and co-lead research in step with the mission of the health system. Biostatisticians are often co-investigators on epidemiologist-lead research, but focus most on statistical issues across multiple projects.• Epidemiologists tend to favor observational studies, but often employ methodologies developed by basic science researchers and team with clinical researchers doing intervention studies. • Investigators who want to use population data to address a research question can benefit from interactions with an epidemiologist.
