I am an experimental psychologist, and I obtained my PhD from UCL investigating decisions from descriptions and experience.
My research focuses on decisions under uncertainty, in particular investigating how individuals combine risk and probability information from different sources when making decisions.
I also research how to create more efficient warnings and disclaimers which can help individuals make better decisions.
Recent research projects include group decision-making in boards of trustees of pension schemes for the Institute and Faculty of Actuaries, and risk and blame attribution by consumers using smart products for the Department for Business, Energy & Industrial Strategy.
Before entering academia, I worked as a management and strategy consultant for corporate and investment banks.
Lecturer in Cognitive Psychology
