John P. A. Ioannidis (born August 21, 1965 in New York City) is a physician-scientist and writer with contributions in evidence-based medicine, epidemiology and public health, data science and clinical research. He has pioneered the field of metascience (research on research). He says that much of the published research doesn’t meet good scientific standards of evidence.
Ioannidis studies scientific studies themselves, in clinical medicine and social science. He is one of the most-cited scientists in the literature, and his 2005 paper “Why Most Published Research Findings Are False”. is the most downloaded paper in the Public Library of Science and has the highest number of Mendeley readers across all science. In response, Ioannidis wrote tongue-in-cheek, “This probably only proves that citation metrics are highly unreliable, since I estimate that I have been rejected over 1,000 times in my life.” He is a Professor of Medicine, of Health Research and Policy and of Biomedical Data Science, at Stanford University School of Medicine and a Professor of Statistics at Stanford University School of Humanities and Sciences. He is director of the Stanford Prevention Research Center, and co-director, along with Steven N. Goodman, of the Meta-Research Innovation Center at Stanford (METRICS). He is also the editor-in-chief of the European Journal of Clinical Investigation. He was chairman at the Department of Hygiene and Epidemiology, University of Ioannina School of Medicine as well as adjunct professor at Tufts University School of Medicine.
