Research Interests
Air/water pollution and climate change are global issues, requiring immediate attention and innovative cross-disciplinary research to understand and mitigate their effects on our planet. To this end, the Slade lab studies fundamental chemical and physical processes affecting the formation, evolution, toxicity, and climate properties of atmospheric aerosols. We are interested in applying and developing novel analytical methodologies (e.g., in mass spectrometry) to understand the detailed multiphase chemistry and kinetics of organic aerosol formation and interactions with gas-phase oxidants and reactive semivolatile species in different environments (urban, coastal, forested, and biomass burning). Our three main thrusts involving both laboratory and field work currently are (1) reactive organic nitrogen multiphase chemistry of urban secondary organic aerosol, (2) chemical aging and toxicity studies of emerging priority chemicals in marine aerosol, and (3) fundamental interrelationships between aerosol phase and composition.
