[2] An overarching theme of Logan's research is how anthropogenic activities influence the composition of the atmosphere.
Broadly, her research includes investigations into how fires impact particles in the atmosphere, how changes in climate impact air quality, the use of satellite data to measure ozone, and modeling efforts that link current and past atmospherical datasets.
[3] After her Ph.D. research on halogens,[4] Logan considered how people influence atmospheric chemistry through actions including biomass burning, agriculture, and the release of chlorocarbons.
[8][9] Her research identified how sulfur-based atmospheric pollutants can form SO2[10] and she presented a global view of inorganic compounds in the troposphere.
[25] In 2001, Logan contributed to the section of Intergovernmental Panel on Climate Change (IPCC) report that covers "Atmospheric Chemistry and Greenhouse Gases".
