Dr. Johnson has over 15 years of experience in environmental exposure and epidemiology. Markey earned her PhD at the University of Michigan conducting community based participatory research to examine housing characteristics, social determinants, and environmental health among Arab Americans. As a postdoctoral fellow at the U.S. Environmental Protection Agency, she designed and conducted participant-based air monitoring, developed land use regression models, and linked air pollution exposure to biomarkers and health. For the past 8 years Dr. Johnson has designed and led studies assessing air pollution exposure and health as a senior researcher in the Air Health Science Division of Health Canada. Her research includes the development of air pollution models integrating land use regression, regulatory monitoring, satellite remote sensing, and chemical transport models – as well as linkage of air pollution and health. Her current interests include critical developmental windows and source-specific exposure and health analyses. Dr. Johnson has been an ISES member for 10 years, currently serves on the ISES Membership and Nominations Committees, and is Co-Chair of the 2018 ISES-ISEE joint meeting in Ottawa.
