Measurement and modeling of urban and regional air pollution. Special interests include:
- Airborne Particulate Matter Measurements: Development of new methods for sample extraction and analysis to quantify particle-phase trace metals and organic compounds in the atmosphere with special focus on ultrafine particles (100nm and smaller).
- Emissions Measurements: Characterization of the size and chemical composition of particle-phase emissions from major sources of urban air pollution with special focus on ultrafine particles (100nm and smaller).
- Development of Parallel Computer Systems and Programs: Design of massively parallel computer system constructed from commodity components, and the optimization of computer codes for these platforms.
- Air Quality Modeling: Estimation of thermodynamic properties of mixed organic and inorganic airborne particles. Development of methods for the regional source apportionment of primary and secondary airborne particulate matter.
- Interactions Between Global Change and Regional Air Pollution: Identification of the current effects of climate variability on regional air quality and prediction of the air quality impacts from future global change trends.
- Health Effects of Inhaled Particles: Identification and characterization of airborne particles responsible for excess morbidity and mortality.
