Biography
Dr. Michelle Bell is the Mary E. Pinchot Professor of Environmental Health at the Yale University School of the Environment, with secondary appointments at the Yale School of Public Health, Environmental Health Sciences Division; the Yale Jackson School of Global Affairs; and the Yale School of Engineering and Applied Science, Environmental Engineering Program. Her research investigates how human health is affected by atmospheric systems, including air pollution and weather. Other research interests include the health impacts of climate change and environmental justice. Much of this work is based in epidemiology, biostatistics, and environmental engineering. The research is designed to be policy-relevant and contribute to well-informed decision-making to better protect human health and benefit society. She is the recipient of the Prince Albert II de Monaco / Institut Pasteur Award, the Rosenblith New Investigator Award, and the NIH Outstanding New Environmental Scientist (ONES) Award. Dr. Bell holds degrees from the Massachusetts Institute of Technology (B.S. in Environmental Engineering), Stanford University (M.S. in Environmental Engineering), University of Edinburgh (M.Sc. in Philosophy), and Johns Hopkins University (M.S.E. in Environmental Management and Economics and Ph.D. in Environmental Engineering). She was elected to the National Academy of Medicine.

The project also examines the effects of air pollution on mortality, whether these relationships differ by SES, and looking at air pollution and weather together. The work is based on three cities: Santiago, Chile, Sao Paulo, Brazil, and Mexico City, Mexico.
