Electricity generation is the leading source of greenhouse gases worldwide. Transitioning to more reliable, affordable, and clean electricity sources is crucial to decarbonizing energy overall. Our group models how wind, solar, geothermal, and other resources can help decarbonize electricity and assesses potential benefits for air quality, climate, and health.

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

Ground-level ozone and particulate matter form from complex interactions among numerous pollutants. Understanding those photochemical processes is crucial to developing cost-effective control strategies.
