Bio

John P.A. Ioannidis (born in New York, NY in 1965) holds the C.F. Rehnborg Chair in Disease Prevention, and he is Professor of Medicine, Professor of Health Research and Policy, and Director of the Stanford Prevention Research Center at Stanford University School of Medicine; Professor of Statistics (by courtesy) at Stanford University School of Humanities and Sciences; one of the two Directors of the Meta-Research Innovation Center at Stanford; member of the Stanford Cancer Institute and of the Stanford Cardiovascular Institute, and affiliate in the Stanford Center on Longevity, and the Woods Institute for the Environment. Ioannidis grew up in Athens, Greece. He was Valedictorian of his class (1984) at Athens College and won many early awards, including the National Award of the Greek Mathematical Society in 1984. He graduated in the top rank of his medical school class from the University of Athens in 1990 and received also a doctorate in biopathology from the same institution. He trained at Harvard and Tufts specializing in internal medicine and infectious diseases, then held positions at NIH, Johns Hopkins and Tufts. From 1999 until 2010 he chaired the Department of Hygiene and Epidemiology at the University of Ioannina Medical School in Greece, as a tenured professor since 2003. He has been adjunct faculty at Tufts University School of Medicine since 1996, with the rank of professor since 2002 and led (2008-2010) the Genetics/Genomics component of the Tufts Clinical and Translational Science Institute (CTSI) and the Center for Genetic Epidemiology and Modeling (CGEM) at Tufts. He has also been adjunct professor of epidemiology at the Harvard School of Public Health and visiting professor of epidemiology and biostatistics at Imperial College London. He is a member of the executive board of the Human Genome Epidemiology Network and senior advisor on knowledge integration at the National Cancer Institute and has served as President of the Society for Research Synthesis Methodology, as a member of the editorial boards of many leading international journals (including PLoS Medicine, Lancet, Annals of Internal Medicine, JNCI, Science Translational Medicine, Clinical Chemistry, Molecular and Cellular Proteomics, AIDS, International Journal of Epidemiology, Journal of Clinical Epidemiology, Clinical Trials, and PLoS ONE, among others) and as Editor-in-Chief of the European Journal of Clinical Investigation since 2010. He has given more than 300 invited and honorary lectures, has received several awards (including the European Award for Excellence in Clinical Science for 2007), has been inducted in the Association of American Physicians in 2009 and in the European Academy of Cancer Sciences in 2010 and was elected Honorary Member of the Foundation for Research and Technology-Hellas in 2014. The PLoS Medicine paper on “Why most Published Research Findings are False,” has been the most-accessed article in the history of Public Library of Science (>1.1 million hits). His Toccata for the Girl with the Burnt Face (Kedros 2012, in Greek) was shortlisted for the best book Anagnostis annual awards in Greece in 2013. His latest book Variations on the Art of the Fugue and a Desparate Ricercar was published in 2014 (Kedros, in Greek). The Atlantic selected Ioannidis as the Brave Thinker scientist for 2010 claiming that he “may be one of the most influential scientists alive”. Apparently, he is one of the most-cited scientists worldwide according to all major citation databases (Web of Science/Highly-Cited Researchers, Scopus, Microsoft Academic Search). Citation indices: Hirsch h=121, Hirsch m=6.0, Schreiber hm=73, 40 papers with >200 citations as single, first or last author per Google Scholar (h=98 per ISI). He considers himself privileged to have learnt and to continue to learn from interactions with students and young scientists (of all ages) from all over the world and to be constantly reminded that he knows next to nothing.

Research & Scholarship

Current Research and Scholarly Interests

I have worked in the fields of evidence-based medicine, clinical investigation, clinical and molecular epidemiology, clinical research methodology, empirical research methods, statistics, and genomics. I have a strong interest in large-scale evidence (in particular randomized trials and meta-analyses) and in appraisal and control of diverse biases in biomedical research. I am interested in developing and applying new research methods, and in the interdisciplinary enhancement of existing research methods for study design and analysis in biomedicine. Some of my most influential papers in terms of citations are those addressing issues of replication validity of genetic association studies, biases in biomedical research, research synthesis methods, extensions of meta-analysis, genome-wide association studies and agnostic evaluation of associations, and validity of randomized trials and observational research. I have also designed, steered and participated in influential randomized trials (in particular, the major trials that changed decisively the management and outcome of HIV infection, but also trials in nephrology, and in antibiotic use in the community), and large international consortia that have helped transform the efficiency of research in diverse fields of genomic, molecular and clinical epidemiology. I enjoy working with a diverse array of colleagues from very diverse disciplines and to have an opportunity to learn from both senior and junior investigators, and particularly students at all levels.
