Our team

We’re an interdisciplinary team, based predominantly at the University of Melbourne, but we have colleagues from Germany, Netherlands, UK and the USA working on our project too. The repliCATS project is a part of Prof Fiona Fidler’s & Prof Simine Vazire’s joint research group, MetaMelb.

Meet the repliCATS project team

Fiona Fidler is a professor at the University of Melbourne, with a joint appointment in the Schools of BioSciences and History and Philosophy of Science. She is broadly interested in how experts, including scientists, make decisions and change their minds. Her past research has examined how methodological change occurs in different disciplines, including psychology, medicine and ecology, and developed methods for eliciting reliable expert judgements to improve decision making. She originally trained as a psychologist, and maintains a strong interest in psychological methods. She also has an abiding interest is statistical controversies, for example, the ongoing debate over Null Hypothesis Significance Testing. She is a current Australian Research Council Future Fellow, and leads the University of Melbourne’s Interdisciplinary MetaResearch Group (IMeRG), and the lead PI of the repliCATS project.

Bonnie Wintle is a research fellow in the School of Biosciences at the University of Melbourne, and a senior researcher in the Interdisciplinary MetaResearch Group (now MetaMelb). She develops structured methods for eliciting and aggregating quantitative and qualitative judgements from groups of experts, to support better decision and policy making. She has pioneered empirical research on the best ways to obtain more accurate group estimates of fact, and applied protocols for eliciting quantitative, probabilistic and qualitative judgements from expert groups that have informed real-world decisions (e.g., to underpin surveillance systems used in industry). She has a background in environmental science and ecology, a history of working closely with philosophers, mathematicians and psychologists, and extensive experience managing interdisciplinary expert groups. Bonnie is a PI on the repliCATS project, leading the Elicitation & aggregation team.

Picture of Hannah FraserHannah Fraser is a research fellow at the University of Melbourne working in Fiona Fidler’s meta-research lab, MetaMelb. She is lead author of Questionable Research Practices in Ecology and Evolution (Fraser et al. 2018), which has received widespread attention (preprint downloaded 679 times). During her PhD, Hannah also gained expert elicitation experience. In 2020, Hannah was president of the Association of Interdisciplinary Meta-research & Open Science, an association she helped found. Hannah was the research coordinator for the repliCATS project in Phase 1, and will be remaining on the project in phase 2 in an advisory capacity.

Mark Burgman is the editor of two books and the author of seven, including Risks and Decisions for Conservation and Environmental Management (Cambridge University Press, 2005) and Trusting judgements: How to get the best out of experts (Cambridge University Press, 2015). In addition, he has published over 250 refereed papers and more than 70 reviewed reports and commentaries. His book on Risks and Decisions outlined the foundations for a range of methods relevant to decision making under uncertainty and foreshadowed the importance of expert judgement and elicitation in empirical studies. In the 1990s, he one was one of the early figures in the development of methods for dealing with the human dimensions of environmental management. From 2006, at the University of Melbourne he led the Australian Centre of Excellence for Risk Analysis and then the Centre of Excellence for Biosecurity Risk Analysis. In 2016, he took up the position of Director of the Centre for Environmental Policy at Imperial College London. He has been the editor-in-chief of the journal Conservation Biology since 2013. The impact factor of his publications (Google Scholar) is 65 and his work has been cited more than 16,000 times. Mark is a PI on the repliCATS project.

Peter Vesk is an Associate Professor and Reader in the School of BioSciences at University of Melbourne. He has a long history of working on generalization and reliability of scientific knowledge before it was known as reproducibility, starting in plant ecology. He is an Associate Editor at Journal of Ecology, the most highly ranked journal in plant ecology. As a founding editor of Hot Topics in Ecology, designed to provide evidence based statements on ecological topics relevant to policy and management, he is keenly interested in participatory methods of providing reliable scientific knowledge. He has > 100 journal articles, with >4700 citations and H=36 (Scopus). Vesk’s research focus is gathering, formalizing and generalizing knowledge for management. This entails attention to methodology of data collection, use and model evaluation. Working on legacy and citizen science data have driven attention to robustness of inference and methodology. Pete is a PI on the repliCATS project.

Simine Vazire is a professor of psychology at the University of Melbourne, and a member of the Ethics & Wellbeing Hub. She studies meta-science and research methods/practices, as well as personality psychology and self-knowledge. Her research interests on the meta-science side include assessing the quality and integrity of scientific studies, the peer review process, and the scientific community at large. She is interested in how transparency and criticism are (or aren’t) used to make science more self-correcting. Her training is in social and personality psychology, and her interests in scientific practices and norms stems largely from her experiences in that field, particularly the so-called replication crisis. She has been an editor at several psychology journals, and co-founded the Society for the Improvement of Psychological Science (SIPS) with Brian Nosek in 2016. Simine will join as PI on the repliCATS project for phase 2.


Community & engagement team

Fallon-ModyFallon Mody is a research fellow in Fiona Fidler’s meta-research group at the University of Melbourne. Her expertise is in science communication, qualitative analysis, and history and philosophy of science.
