Thèmes de recherche

Atmospheric Chemistry, climate

- Surface sources and sinks of trace gases that are important for atmospheric chemistry and the global greenhouse effect, including methane, nitrous oxide, methyl bromide, and methyl chloride. Industrial and biological processes that release and/or consume such gases.

- Stable isotope techniques applied to identifying sources and sinks of atmospheric chemicals.

- Mathematical modeling of atmospheric chemical kinetic processes, including processes that control atmospheric ozone and that limit the lifetime of relatively inert gases.

- Public policy relevant to global climate change and pollution issues.
