Research Interests:
Human activity and natural processes can have measurable impacts on atmospheric composition. These emissions can impact earth’s climate system and outdoor and indoor air quality. An important focus of my research involves the characterization of aerosol particles. We conduct field measurements and laboratory experiments to provide unique insights into the origins, composition, and fate of aerosols in the air we breathe, both indoors and outdoors. Current research projects focus on problems at the leading edge of atmospheric chemistry, which include:
- Sources and formation of atmosphere organic aerosol
- Chemical evolution of biomass burning carbonaceous aerosol
- Photochemistry and oxidative capacity of indoor air
- Environmental inequity in aerosol exposure and chemistry
We help improve the predictive capability to inform policy decisions on issues relating to climate, human health, and welfare.
