Lauren Ferguson is a Postdoctoral Research Fellow with the Healthy Buildings Program. Lauren holds a PhD in Environmental Engineering from University College London (UCL), UK, where she built a personal exposure model which estimated childhood exposure to PM2.5 for 1.3 million individuals in Greater London. The tool can be used to assess a number of “soft” (for example, behavioral modifications) and “hard” (for example, building interventions) policy interventions on childhood exposure to air pollution. Lauren’s interests lie in using building physics and statistical models to assess population-level exposures to indoor environmental hazards, such as heat and air pollution, and understanding how these exposures lead to health impacts and inequalities. In addition to her doctoral research, she has applied these techniques to study population exposure to household air pollution in Nairobi’s informal settlements and predict the extent of indoor overheating the UK housing stock may face under future climate scenarios. The goal of her work with the Healthy Buildings Program is to continue her research into indoor heat, where she will be building a US-based housing stock model.
