Lelia Hawkins 2005-
Lelia is a third-year
graduate student in the Climate
Science curricular group. She is currently finishing her first
manuscript for publication and beginning to design her thesis project
that will involve collecting multiple types of aerosol particle samples
from the SIO pier. The main goal of the experiment is to characterize
the organic and elemental components of coastal marine aerosols using
both filter and aerosol mass spectrometer analyses. She is most
interested in their impact on marine stratocumulus clouds with an
emphasis on implications for climate change. Other projects include:
analysis of filter samples and aerosol mass spectrometer measurements
from the Houston TEXAQS-II, deployment and continued analysis of filter
samples from Barrow, Alaska, and involvement in the 2008 VOCALS
research cruise off the coast of Peru. She received her B.S. in
Chemistry and Environmental Systems from UCSD in 2005.

Alice the Aerosol-Detector Dog (a.k.a Alice the Dog)
Alice has
state-of-the-art nano-bio-detectors that target very low
detection
limits
for carbonaceous particles derived from bovine sources after incomplete
combustion using charred wood and coal fuels. H nano-sensors use
bio-mimicking messengers to track complex compositions with "smart"
adaptive learning algorithms. Other meat-cooking operations will
also be studied, with a special focus on lamb, turkey, and
salmon. Particle analysis is performed online in real-time,
typically resulting in complete digestion of complex proteins and
carbohydrates with highly oxygenated organic functional groups.

Steven
Maria 1999-2004
Steven's research focuses
on the characterization of
atmospheric
organic
particulate matter using a newly-calibrated 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. The
presence or absence of hydrophobic organic compounds
in the atmosphere may significantly affect the ability of aerosol
particles to absorb water and form cloud droplets, but this effect is
poorly understood. To aid in the understanding of this phenomenon,he is
using a multiple-solvent sample rinsing procedure in conjunction with
FTIR analysis to provide an estimate of the organic functional group
water-solubility.

Cynthia Randles 2001-2004
Geophysical Fluid Dynamics Laboratory
NOAA
Princeton, NJ
Cynthia is a fourth year
graduate student in the
Atmospheric
& Oceanic Sciences Department. She is currently interested in 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 Singh 2001-2004
Elizabeth's research
focuses 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 current experimental
setup looks at particles in the size range of 0.01 - 0.30 um.

behaviors of aerosol particles with the Princeton Organic-Electrolyte

Kelly
Kuhns-Kobland 2001-2003
Atmospheric aerosols, when inhaled, may experience significant changes
in size, shape, density, and/or composition as they travel through the
human respiratory system. Kelly used local aerosol characterization
data to
investigate the effects of aerosol dynamics on particulate matter in
the human respiratory tract. This information, in conjunction with
medical studies, provided us with insight into the health effects of
inhaling various New Jersey particulate matter.
