I am interested in developing a quantitative understanding of the origin of air pollutants and the impact of these pollutants on human health and the ecosystem, such that effective control strategies can be developed and designed to mitigate the adverse effects of air pollution. I am concerned with air quality issues relating to indoor, urban, regional and global air pollution.
My research group is developing advanced characterization tools that can be used to determine detailed chemical, physical, and biological characteristics of emissions from air pollution sources and atmospheric pollutants. Such tools provide the basis for air pollution models that can be used to assess the contributions of air pollution sources to atmospheric concentrations of these pollutants, and provide the basis for the development of pollution abatements strategies. In addition, we are using advanced characterization of air pollutants to help assess the impact of air pollution on human health and the environment.
