John P.A. Ioannidis 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 (1996). He trained at Harvard and Tufts, specializing in Internal Medicine and Infectious Diseases, and has held appointments at NIH, Johns Hopkins University School of Medicine, Tufts University School of Medicine, and Harvard School of Public Health. He has been chairing the Department of Hygiene and Epidemiology at the School of Medicine, University of Ioannina, Greece, since 1999 (a tenured professor since 2003). 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 (appointment active as of January 2010).  Dr. Ioannidis is a member of the executive board of the Human Genome Epidemiology Network, President of the Society for Research Synthesis Methodology, 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 Editor-in-Chief of the European Journal of Clinical Investigation for the period 2010-2014. He has given more than 200 invited and honorary lectures. His publication record includes over 400 peer-reviewed papers, over 40 books and book chapters, and several other writings, and he has already received over 20,000 citations in the literature with Hirsch indices h=75, m=4.6 per GoogleScholar as of 4/2010. He has received several awards, including the European Award for Excellence in Clinical Science for 2007, and was elected a regular member of the Association of American Physicians in 2009. 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.
