Michelle L. Bell

Professor of Environmental Health


Our research group addresses air pollution and human health by integrating several disciplines, such as environmental engineering and epidemiology. The overall aim of our work is to answer scientific questions regarding how air pollution affects health and to perform policy-relevant research that contributes to well-informed decision-making and to greater public understanding of environmental health hazards. Much of our work uses mathematical modeling to examine the relationships among air pollution, weather, and human health endpoints such as mortality and hospital admissions. Other work addresses health impacts of weather, the exposure-response curve between concentrations and health risks, and whether heterogeneity in pollution-health estimates can be explained by differences in socio-economic or other characteristics.
