Fields: Climate Change Modeling; Impacts of Aviation; Geoengineering

Lab Role: Research Assistant


I come from Shrewsbury, England, and am currently pursuing a PhD in Aerospace Engineering. My research is broadly focused on the human health impacts of high altitude emissions. Although aviation emissions are a core topic for my research, I am also investigating other emissions such as those related with proposed ‘aerosol shield’ geoengineering schemes. I use global-scale atmospheric models to evaluate the potential positive and negative effects of such emissions, using a variety of metrics.
