Indoor Environmental Quality in SchoolsNew Project with R. Corsi, A. Novoselac, Y. Xu (CAEE), S. Wu (Center for Sustainable Development) and S. Horner (School of Nursing)
• High schools ‐ virtually unstudied environments
• Field campaign in 6 high schools • 120+ Classroom visits & selected
portables• Identifying relationship between health
symptoms and– Environmental Conditions– Microbiome– Chemical contaminants
• Integrating community engagement and research
Related Research• Toxicity of fine particulate matter
(Reactive Oxygen Species in the indoor & outdoor environment)
• Removal of pharmaceuticals and personal care products from water (with D. Lawler and C. Whitman (School of Pharmacy)
• Harvested Rainwater Quality (Kirisits, CAEE)
• Removal of algae & P from water (Katz, CAEE)
