Atmospheric Chemistry

Research in my group is focused on characterizing the emissions and transformations of compounds in the atmosphere. Radical Chemistry in Forests The "ROx" family of trace radicals comprises OH, HO2, and organic peroxy radicals "RO2". These radicals have a central role in atmospheric chemistry: concentrations of OH determine the lifetime of volatile organic compounds (including the greenhouse gas methane) in the atmosphere, and reactions of HO2 and RO2 lead to the formation of ozone and secondary organic aerosol particles, both of which affect Earth's climate and human health. Due to their low concentrations and high reactivity these radicals are difficult to quantify. Our understanding of radical sources and sinks has several gaps, especially in forests where there are relatively high concentrations of reactive biogenic volatile organic compounds. A current NSF-funded project involves developing a new sensor for quantifying peroxy radicals using "chemical amplification" and cavity attenuated phase shift spectroscopy. This new sensor will be deployed during the summers of 2015-2017 to investigate ROx chemistry in forests. Airports and Air Quality Aviation is projected to grow at a much faster pace than the rest of the economy. As a result, the impact of airports on air quality is of growing concern. Two projects funded by the Transportation Research Board focus on updating the tools used by airports to create emission inventories and to predict the concentrations of several pollutants.
