Atmospheric Chemistry & Aerosols

Atmospheric chemistry is the study of the composition of the atmosphere and the interactions that occur between the atmosphere and living organisms. Topics include

  • Photochemical, thermochemical and electrochemical reductive dehalogenation of chlorinated organics
  • Study of aerosols and cloud condensation nuclei
  • Frozen solution chemistry
  • Microphysical and chemical properties of winter precipitation
  • Urban air quality
  • Ground water remediation
  • Investigations of aerosol physicochemical properties (composition, size, hygroscopicity)
  • Investigations of aerosol-cloud interactions
  • Aerosol instrumentation development
  • Chemical transport modeling
