Rachel completed her Masters thesis in 2010 on her work on biogenic aerosols at Whistler. In spring 2008, she sampled at a mid-mountain site in Whistler, BC. Surrounded by forest this is a great location to look at biogenic influences on aerosol chemistry. In winter 2009 she collected sub- and supermicron bulk and single particle measurements up the mountain, at Whistler peak with Environment Canada.

Steve completed his PhD in 2004 and is now a consulting engineer at a defense contractor in New Jersey. His research focused on the characterization of atmospheric organic particulate matter using new aerosol-specific calibrations for FTIR spectroscopy technique. FTIR analysis can quantify organic alkane, alkene, aromatic, alcohol, carbonyl, sulfur, and nitrogen groups, allowing for estimates of total organic carbon (OC) and total organic mass (OM) bulk submicron aerosol concentrations. The resulting OM/OC ratios provide an improved estimate of the conversion factor used to convert from the widely-used thermal-optical OC measurements to total OM.

Cynthia is now a postdoctoral scholar at NASA Goddard in Maryland. She studied the direct effect of atmospheric aerosols (i.e. scattering & absorption of light by aerosol particles) with an emphasis on organic aerosols. In particular, she is interested in how the presence of organics within an aerosol particle can change the particle's hygroscopicity (or, it's ability to take up water), and thus alter the optical (scattering & absorption) properties of the aerosol.

Elizabeth is now an engineer for Dupont Corporation in Deleware. Her research focused on characterizing the size and sodium mass of sea-salt aerosols. The majority of sea salt aerosols are created by bubbles bursting at the ocean's surface. She has created a bubble generator to simulate this aerosol formation under laboratory conditions. After the aerosols are generated, they go into a salt particle counter (SPC) to characterize the sea-salt. The SPC consists of a differential mobility analyzer (DMA) to separate the particles according to their electrical mobility, a condensation particle counter (CPC) to count how many particles are in each size class, and a flame photometric detector (FPD) to thermally dissociate the aerosols to determine their sodium mass concentration. Her experimental setup looks at particles in the size range of 0.01 - 0.30 um.

Her research work focused on the thermodynamics of aerosol particles with an emphasis on modeling the organic compounds present in aerosols. He studied the hygroscopic growth behaviors of aerosol particles with the Princeton Organic-Electrolyte Model (POEM) jointly developed with Prof. Russell. This model helped him to understand the radiative properties of aerosols in the global climate model.
