My interests are broadly in energy and
environmental systems, with specific interests in: 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.

·
Dr.
Frey has openings for graduate research assistantships in three major research
areas: (1) modeling of human
exposure to particulate matter; (2) measurement and modeling of vehicle
activity, fuel use, and emissions using portable emission measurement
systems; and (3) measurement and modeling of vehicle tire/pavement
noise. Anyone interested in graduate
study at NCSU in these topic areas is encouraged to contact Dr. Frey.
·
Dr.
Frey is a recipient of a 2008 NCSU Alumni Association Outstanding Research Award
·
Dr.
Frey has been selected as a Fellow of the Air & Waste Management Association.
·
Dr.
Frey and his students and colleagues delivered six presentations at the CRC
On-Road Vehicle Emissions Workshop, held on March 31-April 2. Topics include real world measurements of activity, fuel use, and
emissions of construction vehicles, modeling
of construction vehicles, reducing idling fuel use and emissions of long-haul
freight trucks, real-world measurement of cement mixers and school
buses, as well as modeling of conventional and advanced vehicle
technologies and their impact on urban scale energy use and emissions.

Dr.
Frey delivered the Chairman’s Air Pollution Seminar at the California Air Resources Board in Sacramento, CA on
January 9, 2008 on the topic of “Identification and Evaluation of
Potential Best Practices for Greenhouse Gas Reductions in Freight
Transportation.” The related final report is available, “Best
Practices Guidebook for Greenhouse Gas Reductions in Freight
Transportation.”
