Research Interests

 Studying the impact of aerosol mixing state, reactivity, and structure on climate through the scattering and absorption of solar radiation and alteration of cloud properties.  Additionally I am interested in the impact of aerosols on human health and providing links between atmospheric aerosol properties and toxicological responses to aerosol inhalation, as well as links between aerosol inhalation and epidemiological studies.  Integrating online (mass spectrometry) and offline (microscopy/spectroscopy) single particle measurements to probe the detailed chemical and physical properties of aerosols  Developing new methods to study heterogeneous reactions between both laboratory and ambient aerosols and trace gases to probe the detailed chemical processes involved in atmospheric aging of particles

Specific Interests: Heterogeneous Reactions on Aerosols, Aerosol Sources and Evolution In the Atmosphere, Microscopy, Spectroscopy, Mass Spectrometry, Nanoparticle Toxicology, Aerosol Light Scattering and Absorption, Field and Laboratory Measurements, Instrument Development
