Dr. Johnston’s research focuses on assessing environmental factors on poor health such as the epidemiology of smoke pollution, as well as health impacts of airborne allergens and heatwaves. Her notable works include human impacts of wildfires, such as public health costs and projected mortality rates from smoke exposure [38,164,165,166]. Her recent works continue to build on research to quantify the health and economic impacts on the public from wildfire smoke [167], as well as other studies aimed at better informing the public of the air quality risk [168].
