My interests are
broadly in energy and environmental systems, including: modeling and evaluation of advanced
energy conversion (e.g.,combustion, gasification) and environmental control
systems; measurement and modeling of real-world fuel use and emissions of
onroad and nonroad vehicles; development and application of methods for
quantification of variability and uncertainty and for sensitivity analysis
in systems models; and exposure and risk analysis. Air pollutant emissions of interest include
criteria pollutants, hazardous air pollutants (“air toxics”), particulate
matter, and greenhouse gases. More
details on my teaching, current and past research activities, publications,
professional advisory
activities, research group, and computer laboratory are available in the links above.

Ye Cao from North Carolina State University will speak on
“Evaluation of the Modeling of Exposure to Environmental Tobacco Smoke
(ETS) in the SHEDS-PM Model” at the Research Triangle Chapter of the Air
& Waste Management Association at noon on Tuesday, October 20, 2009, at
Conference Room C113 of the U.S. Environmental Protection Agency campus in
RTP, NC.
·
Ye Cao and Xiaozhen Liu have received Student Travel
Awards from the Society for Risk Analysis (SRA) to attend the Society’s
Annual Meeting in Baltimore, MD, December 6-9, 2009. Ye Cao received the Student Merit Award
from the Exposure Assessment Specialty Group of SRA for her paper on
“Evaluation of the Modeling of Exposure to Environmental Tobacco Smoke
(ETS) in the SHEDS-PM Model.”
·
Graduate research assistants in Dr. Frey’s group have won
numerous awards in conjunction with the Annual Meeting of the Air &
Waste Management Association (A&WMA), held June 16-19, 2009 in Detroit,
Michigan. Brandon Graver, Ye Cao,
and Xiaozhen Liu received Student Travel Awards from the Research Triangle
Park (RTP) Chapter of A&WMA to attend the Annual Meeting. Ye Cao won an A&WMA Young
Professional Best Paper Award in the area of Environmental Management. Brandon Graver won first place in the
A&WMA Student Poster Competition at the Master’s level.
·
During 2009, Dr. Frey, graduate research assistants, and
colleagues have recently published new
studies in the area of energy and the environment, including: (a) comparison of diesel versus gasoline
light duty vehicles with respect to energy use and emissions; (b) how to
incorporate uncertainty into assessments of air quality, human exposure to
air pollutants, and assessment of adverse health effects; (c) how to reduce
energy use and emissions from construction vehicles; (d) evaluation of the
effectiveness of “anti-idling” techniques for long-haul freight trucks,
such as auxiliary power units and shore-power, at reducing energy use and
emissions during extended idling for rest stops; and (e) assessment of the
effectiveness of E85 versus gasoline at reducing emissions of key
pollutants. See the publication lists for these and
other papers.
