Indoor Atmospheric Chemistry

People spend approximately 90% of their time indoors, yet indoor atmospheric chemistry remains poorly understood. Our group investigates photochemical and oxidation reactions occurring on indoor surfaces and in indoor air, including interactions between ozone and cleaning agents, cooking emissions, and human skin oils.

We have demonstrated that indoor surfaces illuminated by sunlight can produce significant amounts of secondary organic aerosols and reactive nitrogen species, with important implications for indoor air quality and human health.
