I’m the lead investigator of collaborative research carried out at the Pico Mountain Observatory in the Azores (PT) to understand the chemical, physical, and radiative properties of North Atlantic free tropospheric aerosol sponsored by the National Science Foundation. I’m also co-investigator with Dr. Raymond Shaw for the development of a turbulent cloud chamber also sponsored by the National Science Foundation. The cloud chamber will facilitate novel studies of aqueous aerosol and cloud processing of ambient water soluble gases. My primary research interests are to identify organic aerosol constituents from a variety of atmospheric environments. My research group uses advanced mass spectrometry (MS) techniques to identify organic molecules from atmospheric complex mixtures. We’ve participated in a number of ambient and laboratory studies and are compiling a large database of molecular observations to unravel the complex nature of ambient aerosol.
