My research is in exposure assessment: understanding how much pollution people breathe, and how to reduce those exposures. My specific areas of focus are (1) Air pollution impacts of urban form; (2) Air pollution and health impacts of transportation energy consumption, including alternative fuels (biofuels, electric vehicles) and active travel (walking, biking); (3) In situ measurement of fine particles in developing countries.
Two core themes underlying those areas are modeling and measuring spatiotemporal variability in pollution concentrations; and environmental justice: understanding who is more exposed or less exposed to air pollution, how exposures correlate with attributes such as race or income, and how changes in emissions might shift existing exposure gaps.

Research response: COVID-19
In light of the COVID-19 pandemic, several CEE faculty shifted their focus to working on projects aimed at creating and informing a more resilient community.
PNAS top story honor
An article that highlights research by professor Julian Marshall was named one of the “Top 10 stories of 2019.”
Is the air getting cleaner during the pandemic?
With fewer cars on the road, CEE researchers investigate whether air quality has improved.
