I am Professor of Environmental Sciences & Engineering at UNC.
I conduct interdisciplinary research on air pollution and climate change, linking with health, energy and policy. The following topics are interesting to me:
- modeling of ozone and particles on urban, regional and global scales
- global atmospheric composition and radiative forcing of climate
- air pollution science and management
- integrated assessment
- health impact assessment
- international air pollution transport
- integrated planning of air pollution and climate mitigation
