Neil Donahue

Neil Donahue is the Thomas Lord University Professor of Chemistry and Chemical Engineering at Carnegie Mellon University, affiliated with the Department of Chemistry. His research focuses on atmospheric chemistry, organic aerosol, kinetics, reaction dynamics, radical-molecule reactivity, ozonolysis, and mass spectrometry. Donahue's work explores the oxidation chemistry of Earth's atmosphere, particularly the transformation of organic compounds and their impact on aerosol properties and climate. He is also involved in studying gas-phase ozonolysis chemistry and the behavior of short-lived intermediates such as the Criegee Intermediate. His research addresses the health and environmental implications of fine particulate matter and contributes to understanding the complex interactions within atmospheric aerosols.

Neil M. Donahue is a researcher at Carnegie Mellon University focusing on the kinetics and mechanisms of radicals, climate, air quality, and aerosols. His work explores the formation, properties, and impact of secondary organic aerosol, emphasizing the role of semivolatile emissions, photochemical aging, and low-volatility organic compounds in atmospheric particle growth. He investigates the chemical evolution of organic aerosols, including their oxidation states, molecular composition, and interactions with sulphuric acid–amine nucleation. His research also addresses the aging of organic aerosol, bridging laboratory and field studies, and examines the contributions of biogenic emissions and nitrate radicals to atmospheric aerosol formation.
