I study search behaviour and the trade-off between exploration and exploitation across domains as diverse as space, mind, and culture. This work aims to understand how humans navigate complex information environments (e.g., memory, decision making, and creativity) and how these environments evolve and develop in response.
My research uses experiments, big data, network science, natural language processing, machine learning, and mathematical models, with applications to behavioural and cognitive science.
I am the Director of the Bridges-Leverhulme Doctoral Training Centre and the Behavioural and Data Science MSc.
I am a former Fellow of the Alan Turing Institute. I am also a Research Fellow of the Royal Society.
Some fun articles for the casual reader:
Does my algorithm have a mental health problem, published in Aeon.
Masters of reality: the evolution of shamanism, published in Aeon.
