Profile Summary

I am interested in developing measurement and chemical characterization tools to quantitatively understand the origin and impacts of air pollution.  These tools are desgined to address the impacts of air pollution on human health, climate change and sensitive ecosystems, and to support the development of control strategies to mitigate the adverse effects of air pollution.  I am concerned with air quality issues relating to indoor, urban, regional and global air pollution.

  • Profile Summary

    I am interested in developing measurement and chemical characterization tools to quantitatively understand the origin and impacts of air pollution.  These tools are desgined to address the impacts of air pollution on human health, climate change and sensitive ecosystems, and to support the development of control strategies to mitigate the adverse effects of air pollution.  I am concerned with air quality issues relating to indoor, urban, regional and global air pollution.
