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.

Comparing clean air strategies
A CEE-led research team compared strategies for reducing fine particulate matter pollution disparities across the contiguous U.S. While two approaches based on the Clean Air Act didn’t get rid of disparities, a community-specific approach eliminated pollution disparities.
Higher socioeconomic status linked to increased air pollution exposure in China
UW researchers have uncovered that people living in China who have a higher socioeconomic status are actually more exposed to outdoor air pollution.
Housing discrimination and air pollution
A team of researchers, including Professor Julian Marshall, has found that housing discrimination practices dating from the 1930s still drive air pollution disparities in many American cities today.
