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.
