John P.A. Ioannidis currently holds the C.F. Rehnborg Chair in Disease Prevention at Stanford University and is Professor of Medicine and Director of the Stanford Prevention Research Center at Stanford University School of Medicine.  He has previously chaired the Department of Hygiene and Epidemiology at the University of Ioannina School of Medicine in Greece since 1999 (a tenured professor since 2003, on leave since 8/2010).   He was born in New York, NY in 1965 and grew up in Athens, Greece. He was Valedictorian of his class (1984) at Athens College and won a number of early awards, including the National Award of the Greek Mathematical Society, in 1984. He graduated in the top rank of his class from the School of Medicine, University of Athens, in 1990 and earned a doctorate in biopathology. He trained at Harvard and Tufts, specializing in Internal Medicine and Infectious Diseases, and then held positions at NIH, Johns Hopkins University School of Medicine and Tufts University School of Medicine before returning to Greece in 1999. He has been adjunct faculty for the Tufts University School of Medicine since 1996, with the rank of professor since 2002. Since 2008 he has been leading the Genetics/Genomics component of the Tufts Clinical and Translational Science Institute (CTSI) and the Center for Genetic Epidemiology and Modeling (CGEM) of the Tufts Institute for Clinical Research and Health Policy Studies at Tufts Medical Center. He is also adjunct professor of epidemiology at the Harvard School of Public Health where he is teaching a course on evidence-based epidemiology and visiting professor of epidemiology and biostatistics at Imperial College London.  Dr. Ioannidis is a member of the executive board of the Human Genome Epidemiology Network, and has served as President of the Society for Research Synthesis Methodology, as a member of the editorial board of 26 leading international journals (including PLoS Medicine, Lancet, Annals of Internal Medicine, Journal of the National Cancer Institute, AIDS, International Journal of Epidemiology, Journal of Clinical Epidemiology, Clinical Trials, Cancer Treatment Reviews, Open Medicine, and PLoS ONE, among others) and as Editor-in-Chief of the European Journal of Clinical Investigation. He has received several awards, including the European Award for Excellence in Clinical Science for 2007, and was inducted into the Association of American Physicians in 2009 and into the European Academy of Cancer Sciences in 2010. His 2005 paper in PLoS Medicine, “Why most Published Research Findings are False,” has been the most-downloaded article in the history of Public Library of Science and has been described by the Boston Globe as an instant cult classic. His work combines skills in clinical research methodology and evidence-based medicine with the challenges of current molecular medicine and genomics.
