Research Interests
Physical Chemistry, Atmospheric Chemistry, Analytical Chemistry
Dr. Underwood's primary area of research is atmospherically relevant aerosol chemistry. Aerosol are small particles suspended in air. They can have diameters ranging from a few nanometers up to several microns. Because of their size, they can serve as unique reaction vessels for chemistry in the atmosphere. Current areas of reserach involve developing an understanding of the uptake of water on particles smaller then 100 nanometers.
Research Opportunities for Students
Undergraduate students are involved in all aspects of the group's experiments, including designing and building new instrumentation, running experiments, and analyzing data. Dr. Underwood's research students frequently have the opportunity to present their results at regional and national conferences. For more information regarding her group's research and for opportunities for working in her lab, please contact Dr. Underwood.
