This is his personal website and expresses his own interests and opinions -- not those of his employers.He uses theory and computer simulation to explore scientific and societal issues related to air pollutants broadly. Barron’s research advances process-level understanding within air quality models and uses those models to quantify integrated impacts of air pollution at local, regional and global scales. Recent research has ranged from South Florida single source issues to characterizing pollution in Bogotá, Colombia’s largest city. At UF, Barron also taught "Elements of Air Pollution", "Global Air Pollution" and "Energy and the Environment."
