Jeffrey Collett is a professor and department head in the Department of Atmospheric Science. His research focuses on field studies of ambient air quality along with sources of atmospheric pollutants and their impacts. Particular topics of interest include fine particles and their role in regional haze formation, cloud processing of gases and fine particles, and wet and dry deposition of reactive nitrogen species. Recent research has focused on air emissions and impacts from oil and gas development, wild and prescribed fires and agriculture on cloud processing of pollutants on several continents.
Collett was an Office of Naval Research Young Investigator and is a Fellow of the Cooperative Institute for Research in the Atmosphere.
Collett earned his undergraduate degree in chemical engineering from MIT in 1984. He then studied environmental engineering science at the California Institute of Technology, earning his M.S. in 1985 and his Ph.D. in 1989. He was a postdoctoral fellow in atmospheric physics at ETH-Zurich.
