Sarah Dryhurst is a lecturer in risk perception and communication at University College London and a research affiliate at the Centre for the Study of Existential Risk at the University of Cambridge. A psychologist and ecologist by training, she researches how people understand and respond to communications of risk and uncertainty across domains, from climate change to earthquakes to infectious diseases, and how misinformation may influence how people think about these issues and act in response to them. Prior to joining the University College London, Dryhurst was a research associate at the Winton Centre for Risk and Evidence Communication at the University of Cambridge. She obtained her PhD in climate change ecology from Imperial College London, and holds degrees in psychology, zoology, and conservation biology.
