Dr. Mazzoleni’s primary research interests are to identify organic aerosol constituents from a variety of atmospheric environments. Her research group uses advanced mass spectrometry (MS) techniques to identify organic molecules from atmospheric complex mixtures. Her group has participated in a number of ambient and laboratory studies and is complying a large database of molecular observations to unravel the complex nature of ambient aerosol. Currently, Dr. Mazzoleni is 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. Dr. Mazzoleni is 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.
