Fiona is a Professor and Australian Research Council Future Fellow. She originally trained as a psychologist, then moved into philosophy of science, and then environmental decision making. She holds a joint appointment in Environmental Science and History and Philosophy of Science at the University of Melbourne, where she co-leads the MetaMelb (meta)research group. Fiona 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 was the founding president of AIMOS and is currently lead PI of the repliCATS project (Collaborative Assessments for Trustworthy Science).
