Research Interests

• Health Effects - Exposure assessment, and the effects of measurement error on epidemiological analysis.
• Urban and Regional Smog - Characterization of atmospheric transport and transformation; attribution of particulate matter to sources; characterization of measurement quality.
• Visibility Degradation - Theoretical analysis of radiative transfer and particle optics; analysis of haze composition data; assessment of monitoring and regulatory strategies.
• Global Climate Change - Radiative effects and remote sensing of particles.

Research Summary

My current research centers on the analysis and quality-assurance of data from the IMPROVE network (Interagency Monitoring of PROtected Visual Environments) operated for the National Park Service by the Air Quality Research Center. I also retain earlier interests in all aspects of atmospheric visibility, and in qualitative analyses of the equation systems governing particle coagulation and tropospheric photochemistry.
