Charles Simpson is a Senior Research Fellow at University College London, specialising in the health impacts of climate change. After earning a doctorate in particle physics he changed fields, applying his experience in modelling and analysis to urban climate challenges. His work spans modelling and monitoring extreme heat in cities, assessing health risks, and evaluating strategies to mitigate heat through physical and statistical approaches. He is interested in how indoor environments can be better included in health impact assessment relating to heat, and the consequences of increasing air conditioning ownership in temperate countries.
