Philip S. Stevens serves as Rudy Professor and Associate Dean for Faculty Affairs at Indiana University Bloomington's Paul H. O'Neill School of Public and Environmental Affairs, with adjunct status in the Department of Chemistry. His research elucidates chemical mechanisms affecting indoor air quality, regional pollution, and climate change through laboratory, field, and modeling approaches.
Education:
- Ph.D. in Chemistry, Harvard University (1990)
- A.M. in Chemistry, Harvard University (1986)
- B.A. in Chemistry, Oberlin College (1984)
Stevens' work spans atmospheric radical chemistry, indoor pollutant dynamics, and biogenic emission impacts. His group investigates hydroxyl radical sources during cooking, siloxane emissions from personal care products, and radical sinks in forested environments using advanced instrumentation like laser photofragmentation-LIF systems. This research directly informs air quality regulations and climate policy through collaborations with NASA and NSF.
Recent publications reveal intensifying focus on indoor chemical processes, with 8 of 12 papers (2019-2023) examining household activities' air quality impacts. Key themes include nitrous acid (HONO) formation from cleaning products, secondary organic aerosol production from terpenes, and spatial variability of indoor constituents.
Scientific recognition includes:
- Sloan Foundation Grant (2018)
- Indiana University Trustees Teaching Award (2006)
- NSF CAREER Award
Stevens secures major funding from NASA, NSF, Camille and Henry Dreyfus Foundation, and Sloan Foundation. He chairs the Stevens Atmospheric Chemistry Lab, mentoring graduate students in Environmental Science and Chemistry with recent accolades including AGU 2022 best student presentation and AAAR 2020 best student paper awards. His lab coordinates multi-institutional projects like HOMEChem investigating microbial-chemical interactions in built environments.
The Stevens Lab drives innovation through integrated approaches: field campaigns in urban/forested sites, laboratory kinetics studies of oxidation mechanisms, and computational modeling. Current priorities include quantifying radical budgets in complex environments and assessing health implications of indoor secondary pollutants.
