Areas of Research
Current Research Focus:
Focus: Characterizing organic and inorganic acids and aerosol in the atmosphere emitted by Biomass burning and the study their impact on climate.
Negative Ion proton transfer mass spectrometry to Measure: a) Acidities of gas-phase acids; b) Rate of H-transfer; c) Water cluster characterization. The goal ito get estimates of the free energy of hydration of carboxylate ions, and determination of the effective gas phase acidity of hydrated carboxylate ions. (NSF- Funded
Investigate vibrational overtone initiated photodissociation processes that are significant sources of atmospheric radicals using cavity ring down spectroscopy. The vibrational O-H overtone absorption cross sections of carboxylic acids and other OH-containing species are necessary quantities to calculate the photochemical reaction rate constant (J) for reactions initiated by the excitation of the O-H overtone. (NOAA, NSF Funded
Measurement of the Henry's law coefficient and first order loss rate of Isocyanic Acid in Water Solutions-Solubility studies (NOAA-Funded
Measurement of optical properties of biomass aerosols using cavity ring down spectroscopy ( DoD-Current Funding)
