Fiona Fidler is professor of History and Philosophy of Science at the University of Melbourne. She is broadly interested in how experts, including scientists, make decisions and change their minds. Her research examines how methodological change occurs in different disciplines. Fiona is the lead PI on the repliCATS project (Collaborative Assessments for Trustworthy Science). Now its fifth year, repliCATS reimagines the peer review process as a structured expert elicitation, group deliberation and decision-making process. The project has complete post-publication review of over 4,000 social science papers, across 8 disciplines. In 2022, it won the University of Melbourne Excellence Award for Interdisciplinary Research.
