Emissions of reactive nitrogen compounds from soil are important, but potentially underestimated, contributors to atmospheric chemistry.

The Cohan Research Group at Rice University specializes in the development and application of photochemical models to investigate atmospheric processes and inform air quality management. We are especially interested in how energy use impacts the atmosphere, and how air pollution in turn impacts human health. Current research includes simulating the formation of ozone and particulate matter; modeling the emissions of reactive nitrogen species from soils and the impact of agricultural practices; assessing the air quality, climate, and economic impacts of electric power generation and alternative fuel vehicles; and chronicling U.S. efforts to address climate change.

Emissions of reactive nitrogen compounds from soil are important, but potentially underestimated, contributors to atmospheric chemistry.
Meteorology strongly influences the formation of ozone and particulate matter. Our research is exploring how trends in meteorological conditions under a changing climate are impacting air pollution in the Houston region.
Electric vehicles are becoming increasingly viable options to replace traditional cars, trucks, and buses. Natural gas and fuel cell vehicles are also available in some cases. Our research is comparing the life cycle costs and air pollutant greenhouse gas emissions of each type of vehicle.
