Division, Sacramento, CA

Air Pollution Specialist

Aug. 2005 - present

Generated, interpreted and summarized technical literature on air pollution

topics to aid the protection of public health. Management of contract

research investigating the air quality impacts from agricultural practices

in California. Designed and executed air quality research, advancing the

scientific knowledge of ozone emissions from indoor air cleaning devices

and the measurement of greenhouse gas source emissions.

. Oversight of a $600,000 project to assess greenhouse gas stationary

source emissions throughout California using mobile measurement

platforms. Developed the project work plan, budget, quality

assurance/quality control plan, standard operating procedures, and field

research test plans. Performed data collection, processing and technical

summarization. Established research collaborations and navigated

stakeholder interactions.

. Developed regulatory document limiting ozone emissions from indoor air

cleaning devices sold within California. Managed public workshops and

stakeholder interactions. Participated in the federal electrical safety

standard test method revision.

Graduate Research Assistant

June 2001 - Sept. 2008

Performed organic chemical analysis of motor vehicle emissions samples for

the speciation of the semi-volatile components. Operation and maintenance

of trace-level chemical analysis equipment, including gas chromatographs,

high performance liquid chromatographs (HPLC), spectrophotometers, and ion-

trap mass spectrometers (ITMS). Developed standard operating procedures for

laboratory and field research techniques, and generated their technical

documentation. Organization and development of proper laboratory chemical

documentation and safety protocols for environmental health and safety

audits.

. Developed and validated a novel HPLC-ITMS chemical analysis method to

quantify trace-level carbonyl compounds, specifically quinones, in motor

vehicle gas- and particle-phase emissions.

. Collected gas-phase and size-resolved particle-phase emissions of motor

vehicles operating on chassis dynamometers. Operation and maintenance of

air sampling equipment including cyclone manifolds, annular denuders,

filter media, impactors, mass flow controllers, and vacuum pumps.

Performed proper sample collection and storage techniques to ensure

sample validity and integrity. Performed wet chemical extractions in

preparation for chemical analysis.

. Assessed the photolytic stability of quinones in solution. Acquired

quinone absorption spectra using an ultraviolet/visible absorption

spectrophotometer, performed simulated actinic exposure experiments, and

processed experiment sample analyses using HPLC-ITMS chemical analysis

methodologies.

California Peptide Research, Inc., Napa, CA

Laboratory Technician

Oct. 2003 - May 2004

Isolated and purified organic synthesis target peptides and reaction

intermediates. Operated and maintained a HPLC with spectrophotometer

detector. Prepared laboratory reagents and packaged synthesized materials

for shipment.

Department of Plant and Soil Sciences, Oklahoma State University,

Stillwater, OK

Research Assistant

Sept. 1999 - May 2001

. Executed laboratory experiments to ascertain the bioavailability of heavy

metals from a variety of media. Evaluated an in-vitro method simulating

digestion to determine Arsenic (As), Lead (Pb), and Cadmium (Cd)

bioavailability in contaminated soils. Extracted bioavailable As, Pb, Cd

and Zinc (Zn) from plant and soil samples using wet chemistry methods.

. Designed experiments to assess phosphorus runoff control options for land

application of animal confinement waste. Performed controlled greenhouse

experiment data collection and executed representative field research

studies.
