Research Interests:

Gas-phase atmospheric chemistry of organic compounds emitted from anthropogenic and biogenic sources. This includes the experimental investigation of the kinetics, products, and mechanisms of the gas-phase reactions of organic compounds with hydroxyl (OH) radicals, nitrate (NO3) radicals and ozone (O3). Much of the focus is now on the products and mechanisms of these reactions, using gas chromatography, in situ Fourier transform infrared spectroscopy, and in situ atmospheric pressure ionization tandem mass spectrometry for product analyses.
