[1] During her undergraduate degree she decided she would pursue studying, and chose to for academics who were becoming increasingly interested in air quality and environmental issues.
She has created the methodologies to evaluate the consequences of pollution on precipitation, leading to a better understanding of the impact of aerosols on cloud formation and evolution.
In 2015 Kreidenweis was awarded a $7.5 million United States Naval Research Laboratory grant to characterise aerosol particles in coastal regions.
[9] In this capacity, she is a member of the National Science Foundation program Western Wildfire Experiment for Cloud Chemistry, Aerosol Absorption and Nitrogen (WE-CAN).
[10] The program looks to understand the chemistry in western wildfire smoke, which has significant impacts on air quality, climate, weather and nutrient cycles.
[12] Kreidenweis is interested in the characteristics of atmospheric particles that are responsible for compromised visibility, and has extensively studied the impacts of wildfires.
