I am a postdoc at Birkbeck College (University of London) working with Professor Ulrike Hahn on the Percyles project, investigating threats to deliberation in digital democracy platforms.
I am also an incoming Affiliated Lecturer at Cambridge, where I am finishing up a postdoctoral project with Dr Lee de-Wit, co-supervised with Dr Jens K. Madsen at LSE. The project looks at perceptions of media independence and rational polarisation, and is funded by the Templeton World Charity Foundation.
I am also Lead Researcher on the MHP Polarisation Tracker, a bi-annual survey of polarisation in the UK funded by MHP Group and the Political Psychology Lab. Research from the tracker has been covered by the Sunday Times, and has fed into several publications.
I am interested in applying theories and methods from cognitive science to political psychology, which more normally draws upon social psychology. My research combines computational modelling, experiments, and analysis of large-N survey data. I have a particular interests in studying polarisation and using Bayesian Networks and Agent-Based Simulations. I have a firm commitment to Open Science.
I enjoy teaching, with experience teaching Judgment and Decision Making, Statistics, and programming, particularly R.
In 2025 I was awarded the Anne Treisman Prize by the Department of Psychology, University of Cambridge for the best paper by a postdoctoral researcher for the article Young, Madsen and de-Wit (2025) Belief Polarization Can Be Caused by Disagreements Over Source Independence: Computational Modelling, Experimental Evidence, and Applicability to Real-World Politics. Cognition, 259, 106126. https://doi.org/10.1016/j.cognition.2025.106126
In 2019 I was awarded the Plotkin Prize by the Department of Psychology, University College London for best undergraduate dissertation.
I particularly enjoy creating data visualisations. Here are some of my favourites, all made using ggplot2:
