Methods Executive Membership

The Membership of the Methods Executive

Below are short biographies for the members of the Methods Executive. 

Su Golder is an Associate Professor at the Department of Health Sciences within the University of York, York, UK. She is a qualified information specialist, researcher, and experienced methodologist. She has worked in lots of different settings and has a breadth of experience in supporting systematic reviews of healthcare interventions for over 20 years. She has specialist expertise and teaching experience in systematic review methodology - particularly systematic reviews of adverse effects and collecting data from unpublished sources and social media. Her PhD on optimising the retrieval of adverse effects data was funded by the MRC and has made an important contribution to the retrieval of information on adverse effects both nationally and internationally. Her current research is on the use of unpublished data, text mining and social media to maximise the efficiency and effectiveness of the retrieval of adverse effects data and has been funded by the National Institute for Health Research (NIHR). She has been a co-convenor of the Cochrane Adverse Effects Methods group since its inception in 2007, is a member of the Cochrane Information Retrieval Methods Group, has peer reviewed Cochrane Colloquium abstracts for some years, provided advice and support for Cochrane authors and is a Cochrane review author herself. 

Tianjing Li is an Associate Professor in the Department of Epidemiology at Johns Hopkins Bloomberg School of Public Health, USA, and currently based at the Department of Ophthalmology, School of Medicine, University of Colorado Denver, USA. As well as Co-Convening the Cochrane Comparing Multiple Interventions Methods Group, Tianjing has worked with Cochrane in various capacities over the last 15 years, including as Associate Director of Cochrane United States from 2012 to 2018, serving on the Centre Director Executive from 2016-2018, and as Coordinating Editor for Cochrane Eyes and Vision. She is also an Associate Scientific Editor of the recently launched Cochrane Handbook for Systematic Reviews of Interventions. Outside of Cochrane, Tianjing serves as a Co-Editor-in-Chief for the journal Trials and the Reviews 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. She has taught numerous courses and workshops internationally on methods for systematic review, clinical trial, and epidemiology, including the Risk of Bias 2 tool and network meta-analysis. Tianjing’s research interests span the scope of more than half of the Cochrane Methods Groups, including network meta-analysis, adverse events, priority setting, bias, patient-reported outcomes, qualitative research, GRADE, rapid reviews, and information retrieval. 

Joanne McKenzie is an Associate Professor (Biostatistician) at the School of Public Health and Preventive Medicine, Monash University. She has holds an NHMRC Career Development Fellowship and leads a programme of research on methods for evidence synthesis within the Biostatistics Unit. Her research interests include examination of approaches for meta-analysing results from interrupted time series studies; methods for overviews of systematic reviews, including how to assess the certainty of evidence in overviews; methods for presenting and synthesising results when meta-analysis is not possible; methods to synthesise evidence from multiple treatments (also known as network meta-analysis); and examination of bias in the systematic review process. In addition to her research interests in evidence synthesis, Jo is involved in research examining statistical, bias and reporting issues in multi-stage cluster randomised trials.  Jo is an active contributor to Cochrane, including being a member of the Methods Executive, a Co‐Convenor of the Statistical Methods Group and a co‐author on several chapters of the 2019 edition of the Cochrane Handbook for Systematic Reviews of Interventions.

Silvia Minozzi is a medical doctor with postgraduate Masters in Public Health; she is based at the Department of Epidemiology, Lazio Regional Health Service, Rome, Italy. She also works as a consultant for universities and regional health services as an expert in the production of systematic reviews and clinical guidelines. She is the quality advisor for the Cochrane Drugs and Alcohol Review Group since 2004, Methods Editor since 2015 and is now Joint-Coordinating Editor. She teaches numerous courses and workshops on principles and methods of evidence-based medicine, clinical epidemiology, methods for systematic review, including the Risk of Bias 2 (RoB 2) tool, and clinical guidelines according to the GRADE methodology. She has been involved, as an evidence review team member, in the production of several national and international guidelines. She has published about 100 systematic reviews within and outside of Cochrane and several papers on the evaluation of the inter-rater reliability and usability of risk of bias tools, including ROBIS, ROBINS-I and RoB 2. With her experience, Silvia understands the challenges authors face with complex methods and the needs to mediate between clinical relevance, timeliness and rigors of methodology. Her research interests are in building the transferability and applicability of new methodological standards in review production, with an emphasis on author and clinician needs as reviews become increasingly complex.  

Karel G.M. (Carl) Moons is Professor of Clinical Epidemiology and Director of Research at the Julius Center for Health Sciences and Primary Care at the Universitair Medisch Centrum (UMC) in the Netherlands and affiliated with VanderBilt University (US). His experience covers the full range of design, conduct, data analysis, reporting and dissemination of medical research and its findings. This varies from primary research on the evaluation of medical devices and tests for diagnosis, prognosis, screening and monitoring, to etiological studies and randomised therapeutic trials, to meta-epidemiological studies using aggregate and individual participant data. His main focus concerns improving the methods and approaches for evaluation and implementation of medical devices, (bio)markers and prediction models. He has been involved in >500 peer reviewed publications, books and book chapters, and principal investigator in numerous international clinical studies and networks funded by various international organisations (EU, NHS, NIH). He is chair of the Dutch Reporting and Expert center for Unintended effects of Implants and co-initiator of the new nationwide initiative ‘Health Innovation Infrastructure (Hii) Holland’, that aims to bring new medical devices in a responsible way to the healthcare system. He Co-chairs the Methods Executive and is a Co-convenor of the Prognosis Methods Group. 

Sarah Nevitt is a Research Associate in the Institute of Translational Medicine at the University of Liverpool, UK. She has been an active Cochrane author and Cochrane Methods enthusiast since 2011 and is currently the Statistical Editor of the Cochrane Epilepsy Group and the Cochrane Neuromuscular Group. She is also an active member of the Mental Health and Neuroscience Network. Sarah has worked with many Cochrane Review Groups and Cochrane Methods Groups and has authored and supported Cochrane authors on hundreds of Cochrane reviews including a number of complex review designs, such as network meta-analyses, individual participant data meta-analysis, diagnostic test accuracy reviews and prognosis reviews. Sarah  has facilitated workshops on behalf of the Cochrane Statistics Methods Group at Cochrane Colloquia and served on the Thomas C Chalmers Award Committee for the recent Cochrane Santiago virtual Colloquium. She has an active research interest in the impact of data transparency on evidence synthesis, which was the focus of her 2017 PhD thesis, including the value of unpublished data such as clinical study reports for secondary research such as Cochrane Reviews. She is particularly keen to explore optimising how Cochrane groups can take on an increasing number of complex review designs to address their priority questions and deliver these reviews to the high quality expected of Cochrane with limited resources available.
