Pollutant emissions to the atmosphere have consequences for terrestrial and aquatic ecosystems, as well as for human health. The spatiotemporal distribution of emissions depends on the amount and form of the pollutant, as well as the processes that occur once the pollutant is released to the atmosphere. In my research and teaching, I consider the atmosphere as an integral part of the greater Earth system and I examine the ways that both natural and anthropogenic processes can perturb that system. I am particularly interested in how energy generation affects both air quality and climate. I investigate the chemical reactions and transport pathways that occur in the atmosphere between emission sources and receptors, processes which critically govern the environmental fate of pollutants.
