Investigates the chemistry and impacts of urban indoor air pollution


The Ditto group’s research investigates the relationship between indoor and outdoor air quality in urban areas. Since we spend so much of our lives indoors in our residences and workplaces, Ditto's research strives to answer questions like:
   • What are the impacts of poor outdoor air quality and variable building quality on indoor chemical exposures?
   • What are the impacts of our daily indoor activities on the outdoor environment?
   • What are the health impacts of our indoor activities and exposures?

Her research team combines mass spectrometry techniques in the laboratory and field to examine organic gases, aerosols, and their chemical transformations. Ditto's team collaborates across disciplines to inform new engineering to mitigate the human health and environmental impacts of urban indoor and outdoor air pollution.


Jenna Ditto earned her PhD in 2020 from the Department of Chemical and Environmental Engineering at Yale University, where her research focused on developing new tools to study the chemical makeup of particulate matter in the atmosphere. She then completed her postdoctoral training at the University of Toronto. Working jointly in the Chemical Engineering and Chemistry departments, her research centered on understanding factors that affect indoor air quality. She earned the Wagner Award for Women in Atmospheric Sciences in 2019 and participated in 16th Atmospheric Chemistry Colloquium for Emerging Senior Scientists (ACCESS). She will join the faculty Jan. 1, 2023.
