About John's Work

John C. Bailar III is a physician and biostatistician who specializes in studying and improving the quality of scientific data.

Much of Bailar’s research has concerned the problems of statistical representation of data, peer review, and the ethics of publication.  He helped to establish, and was the chair of the Editorial Policy Committee of the Council of Biology Editors, whose major purpose is to define and explore the responsibilities of scientific journal editors.


Bailar is a scholar-in-residence at the National Academy of Science and a professor emeritus in the Department of Health Studies at the University of Chicago.  He was a professor of epidemiology and biostatistics on the Faculty of Medicine at McGill University (1993-1995) and served as a statistical consultant for the New England Journal of Medicine (1980-91).  He is also affiliated with the Health Effects Institute, a research partnership between the Environmental Protection Agency and the automotive industry, where he serves as a member of their review committee and as an investigator studying the health effects of particulate air pollution.

Bailar received a B.A. (1953) from the University of Colorado, M.D. (1955) from Yale University, and Ph.D. (1973) from American University.
