Research summary
AI-generated

P. S. Stevens studies the chemistry of the air we breathe, focusing on highly reactive molecules called radicals (such as hydroxyl, HO2, and RO2) that drive how pollutants form and break down. This work combines laboratory experiments, computer modeling, and field or indoor measurements to understand air quality in settings ranging from forests to homes affected by cooking and scented consumer products. The research also involves developing instruments to detect these short-lived chemical species.

Publication activity was higher in the late 2010s (roughly 9-18 papers per year) and has slowed in recent years, averaging about 4 per year over the last five years.

Collaborators per year
Distinct co-authors at Indiana University each year — a rough indication of whether the group around this researcher has been growing or contracting. An estimate from co-authorship, not a roster: collaborators are not necessarily lab members, and recent years can be under-counted while indexing catches up.
