President Georgia Salanti Georgia Salanti studied Mathematics in Greece, Epidemiology in Belgium and Sociology in the UK. She has a PhD in Statistics from the Ludwig-Maximillians University of Munich in Germany. She is now associate professor in Biostatistics and Epidemiology at the University of Bern in Switzerland. Before that, she was associate professor at the University of Ioannina in Greece and postdoctoral researcher at the MRC Biostatistics Unit in Cambridge, UK. She has been working in the field of evidence synthesis since 2003 and has contributed to the methodology of meta-analysis and systematic reviews. She participates in the European Network of HTA Agencies (EUnetHTA) Joint Action 3 (2016 - 2020) funded by the European Commission, representing the Swiss Network for Health Technology Assessment. She has participated in several guideline and methodological WHO meetings. In 2010 she received the Award L'Oréal-UNESCO "Women in Science” for her research achievements. She has been working with the Cochrane Collaboration since 2004 and initiated the Cochrane Comparing Multiple Interventions Methods Group that shapes the Cochrane Collaboration’s policy for network meta-analysis. Her recent research interests include the optimal use of real-world evidence in meta-analysis, dose-response models and methods for predicting heterogeneous treatment effects in comparative effectiveness research. Her work is been supported by the Swiss National Science Foundation, the European Research Council and the European Commission.

President-Elect Tianjing Li Dr. Tianjing Li is an Associate Professor in the Department of Epidemiology at Johns Hopkins Bloomberg School of Public Health in Baltimore, Maryland, USA. The primary goal of Dr. Li’s research is to develop, evaluate, and disseminate efficient methods for comparing healthcare interventions and to provide trust-worthy evidence for decision-making. Dr. Li has worked with Cochrane in various capacities for 15 years. Currently, in addition to her new role as a Coordinating Editor for Cochrane Eyes and Vision, she co-convenes the Cochrane Comparing Multiple Interventions Methods Group. She is an Associate Scientific Editor for the 2nd edition of the Cochrane Handbook for Systematic Reviews of Interventions. Outside of Cochrane, Dr. Li serves as an Editor-in-Chief for the journal Trials and the Review Editor for JAMA Ophthalmology. She is an elected member of the Society for Research Synthesis Methodology and was awarded the Society’s inaugural Early Career Award in 2016.
Past President 2019 — 2021 Jack Vevea Jack L. Vevea majored in Classical Greek as an undergraduate and subsequently worked in the printing industry until he was in his early 30s. At that point, he returned to university, studying psychology and mathematics, and completed a doctorate in educational statistics at the University of Chicago under the mentorship of Larry V. Hedges.  He has been a professor at the University of North Carolina, Chapel Hill, the University of California, Santa Cruz, and, currently, the University of California, Merced.  His work focuses on difficult statistical challenges in psychological and educational research. He is particularly active in the field of meta-analysis, working on issues related to random- and mixed-effects statistical models and on the problem of publication bias. He relishes this opportunity to state, once again, that publication bias is not a problem of meta-analysis, but, rather, a problem of how we do research. Indeed, in the context of meta-analysis, we have our only opportunity to assess (and perhaps correct for) publication bias.
Secretary Hayley Jones Hayley Jones is a Senior Lecturer in Medical Statistics at the University of Bristol, UK. She completed her PhD in Biostatistics at the MRC Biostatistics Unit, University of Cambridge, focusing on Bayesian modelling of healthcare performance indicators and identification of unusual performance (“provider profiling”). Following completion of her PhD in 2009, she moved to the University of Bristol, where she moved her primary focus to evidence synthesis methodology while continuing to specialise in Bayesian methods. Her current primary research interest is methodology for meta-analysis of diagnostic test accuracy. She has also developed, and maintains a longstanding interest in, Bayesian evidence synthesis models to estimate the size of hidden populations (for example, the prevalence of opioid dependence) from multiple data sources. Other interests include methods for meta-epidemiology and interpretation and sources of statistical heterogeneity in meta-analyses.

Treasurer Ian Salandha Ian Jude Saldanha is a former physician (Grant Medical College, Mumbai, India) who then trained in public health, epidemiology, clinical trials, and evidence synthesis (MPH and PhD from the Johns Hopkins University Bloomberg School of Public Health in Baltimore, Maryland, USA). Dr. Saldanha is an Assistant Professor of Health Services, Policy, and Practice, and of Epidemiology, at the Brown University School of Public Health. He is the Assistant Director of the Brown Evidence-based Practice Center. He researches outcome use in clinical research, outcome measurement, and technology for evidence synthesis, and has conducted evidence syntheses on a wide range of topics. He has served as an evidence synthesis expert committee member on a couple of committees for the National Academies of Science, Engineering, and Medicine. Dr. Saldanha serves as an editor for the journal Systematic Reviews and for the Agency for Healthcare Research and Quality Effective Healthcare Program.
