Our research activities are focused on understanding the identities, occurrence and transformation of aerosol organic compounds. Changing aerosol composition affects aerosol physical properties and hence affects aerosol-climate interactions. First, we exploit advanced mass spectrometry methods such FT-ICR MS to identify and characterize aerosol organic compounds by their empirical formulas. This identification step is furthered by MS/MS analysis to investigate the structural aspects of individual organic compounds. Since atmospheric organic matter is very complex, we also work with advanced liquid chromatography techniques for increased analyte resolution and identification. Our samples, are collected from a variety of ambient environments and are generated in house to explore secondary organic aerosol components. We are especially interested in aqueous reaction pathways and thus are developing a reaction chamber for investigation of aerosol-droplet chemistry.
