Julian Marshall is the John R. Kiely Endowed Professor In the Department of Civil & Environmental Engineering at University of Washington.

Marshall's research is at the intersection of air quality engineering and public health: understanding how much pollution people breathe, and how to reduce those exposures. His specific areas of focus are

(1)  Mechanistic and empirical modeling of air pollution, to understand how concentrations vary in space and time, and how concentrations and health impacts would change in response to changes in emissions.

(2)  Measuring and modeling air pollution exposures in developing countries (at present, mainly India), including how exposures change in response to interventions.

(3)  Environmental justice: understanding who is more exposed or less exposed to air pollution, how those exposures correlate with demographic attributes such as race and income, and how exposure disparities might shift if emissions from specific sources were to increase or decrease.

Before coming to UW in 2016, Marshall was at University of Minnesota, where he founded the Masters International program in Environmental Engineering and, with Fred Rose, the Acara program in social entrepreneurship. At UW, Marshall founded the Grand Challenges Impact Lab (GCIL). GCIL offers a winter-quarter class in Bangalore, India, where students work with local organizations to apply tools of social innovation to local problems, such as rural education, sanitation, low-income housing, public health, migration, and more.
