Personal background

Dr Tomas Folke joined the CBR in 2018 after finishing his PhD in Psychology from the University of Cambridge. His PhD topic was the role of confidence in perceptual and value-based decision-making. During this time he was the team leader for the Neuroscience and Cognition branch of the Policy Research Group’s Junior Researcher programme and taught Bayesian statistics as a teaching assistant at the Essex Summer School in Social Science Data Analysis. Prior to his PhD he completed an MPhil in Social and Developmental Psychology (Distinction) at the University of Cambridge and a BSc in Psychology at the University of York.

His current research focuses on applying behavioural science to improve human-AI collaborations by making AI more understandable to humans and humans more understandable to AI. He works with a multidisciplinary team of mathematicians, computer scientists and cognitive scientists on projects related to artificial social intelligence and AI explainability. Tomas is also interested in quantitative methods in the behavioural sciences, specifically the relationship between research design and analysis methods, the application and misapplication of statistical modelling, and the potential of big data and machine learning to provide novel behavioural insights.
