Shannon Capps

Shannon Capps, PhD

Assistant Professor of Environmental Engineering

College of Engineering



Capps leads the Drexel Atmospheric Modeling Lab, where her group studies how the location of fossil fuel and other emissions affects public health and climate endpoints through ozone production, aerosol formation and cloud brightening. Her research centers on modeling outdoor air quality and atmospheric behavior in regions that have been or could be affected by externalities of fossil fuel extraction, transport, refinement and consumption.


The Atmospheric Modeling Lab is helping to develop and test the latest air quality modeling programs to estimate the influence of emissions sources on health, ecosystem, and climate impacts of pollutants. Its modeling focuses on the human effect of pollution by projecting impacts over a short time period—up to one year—and at a regional scale, to help inform environmental decision making.

    Suffocating Ozone — Policies That Stem Emission of Precursor Chemicals Save Lives and Crops

    An international team of environmental and atmospheric scientists have pinpointed the chemical emissions that contribute the most to the harmful air quality conditions that are choking more and more cities and causing health problems and reducing agricultural production across the United States. The findings suggest that targeted policies could be more effective in limiting the formation of ground-level ozone, like smog, which contributes to tens of thousands of respiratory related deaths and nearly a billion dollars of crop loss each year.

    People Aren't The Only Beneficiaries of Power Plant Carbon Standards

    When the Environmental Protection Agency finalized the Clean Power Plan in 2015 it exercised its authority to regulate carbon dioxide emissions to protect public welfare. The Plan, now the focus of escalating debate, also put the nation on course to meet its goals under the Paris Climate Agreement. Given that other pollutants are emitted from power plants—along with carbon dioxide—research has shown that carbon emission standards for the power sector benefit human health. New research released today shows that they would also benefit crops and trees.
