Harry Fox has been a PhD candidate at the Complexity Science Hub since October 2025.

Harry is a physicist by training who now works on applying ideas from statistical mechanics and related concepts to problems in economics, sociology, and group psychology. He is particularly interested in problems around societal collapse (and particularly, how it might be avoided); the Ising model and how it can be applied to group behavioural dynamics; attitudes towards and the effects of economic inequality; and heterogeneous models of price formation. At CSH, he works at the intersection of the research areas Collective Minds and Social Complexity and Collapse.

Harry graduated in 2022 with a master’s degree in physics from Imperial College, London, having studied for a semester abroad at the EPFL in Lausanne. His master’s thesis focused on solid-state physics, and in his final year he specialised in quantum information theory and statistical mechanics. After graduating, he worked for two years in cyber security before starting his PhD at CSH.
