Pamela Barfield

Ms. Barfield currently works in the coatings research laboratory of ECPB. Before joining the EPA, she worked for the North Carolina Department of Agriculture. She received a B.S. in chemistry from North Carolina State University and an M.S. in analytical chemistry from the University of North Carolina at Chapel Hill.

Lee Beck

Mr. Beck has been with EPA since 1971, and with APPCD since 1988. His work in ECPB is primarily involved with the fine particulate emissions program, specifically with continued development and deployment of the "Dilution Sampler" and the SPECIATE database.

From 1988 - 2003, Lee assisted APPCD's global climate research program in the Atmospheric Protection Branch, part of that time as Team Leader for the Technology Applications Assessment and Co-control Team. Three comprehensive software packages which were developed under Lee's direction are GloED (Global Emissions Database), GloTech (Global Technology Database), and GloTEM (Global Technology Evaluation Model). These are tools that have not been rigorously validated or been through quality assurance and as such are for internal use only.

Lee's recent publications include technical papers on GloED, GloTech, a Data Attribute Rating System (DARS), and sources of nitrous oxide emissions. He has published more than a dozen technical papers since joining APPCD, and has made more than 20 presentations to domestic and international research organizations regarding his work in Global Climate Research. He was a contributing author for the Encyclopedia of Global Environmental Change published by John Wiley and Sons in 2001.

Prior to joining APPCD, Lee served on the staff of the Emissions Standards Division of EPA's Office of Air Quality Planning and Standards, where he received the Bronze Medal for his work in developing and implementing the Control Technology Center. Prior to that, Lee served as Lead Engineer for the development of more than 18 New Source Performance Standards and National Emission Standards for Hazardous Air Pollutants.

Kerry Bullock

Dr. Bullock joined the EPA in 2003, after receiving a B.S. in Engineering Science from Trinity University and a Ph.D. in Chemical Engineering from the Georgia Institute of Technology. Her current research interests include sampling of fine particulate matter (PM 2.5) and source apportionment modeling.

Bruce Harris

Mr. Harris received a B.S. in Mechanical Engineering and an M.S. in Environmental Engineering from the University of Florida. Mr. Harris has 30 years' experience with the air pollution control technology group of EPA's Office of Research and Development. Mr. Harris primarily concentrates on the development of measurement techniques to allow evaluation of prototype control technologies. Current interests include on-road emission factor development for heavy-duty diesel vehicles, open-path FTIR measurement of emissions from agricultural and waste operations and particle sampler performance evaluations.

Michael Hays

Since joining the EPA, the central research focus of Dr. Hays aims to develop physical and chemical characterization methods to advance fine particulate matter (PM2.5) analysis. His work implements large-volume injection, thermal desorption, and adapted solvent extraction techniques. Laboratory and field study objectives are devised in tandem to provide: (1) organic chemical signatures of PM2.5 emissions from a wide array of combustion-related air pollution sources, (2) input to source-receptor models used in apportionment efforts and for source reconciliation, and (3) practical understanding of gas/solid phase partitioning of semivolatile organic pollutants. Dr. Hays received both his B.S. degree in Chemistry and Ph.D. in Environmental Studies from the University of Massachusetts Lowell. Prior to joining the ECPB at EPA, he spent two years as a postdoctoral research associate at Case Western Reserve University in Cleveland, OH, where he studied economical and efficient sorbents for uptake of sulfur dioxide.

Larry Jones

Mr. Larry G. Jones is Chief of the Emissions Characterization and Prevention Branch (ECPB) in the Air Pollution Prevention and Control Division (APPCD), National Risk Management Research Laboratory (NRMRL), in the Office of Research and Development (ORD). He manages research programs and supervises staff to characterize and assess source emissions of criteria pollutant gases, fine particles, and hazardous air pollutant (HAP) emissions and programs to prevent volatile organic compound (VOC) and HAP emissions. In his current assignment, he directs research into remaining uncontrolled or inadequately controlled sources of air pollution.

Mr. Jones joined EPA in 1971 after 5 years in private industry in polyester chemical processes and Naval munitions production and design engineering of submarine intercontinental missiles and torpedo batteries. Since coming to EPA, his experience includes 13 years in the Office of Air Quality Planning and Standards (OAQPS), where he developed New Source Performance Standard (NSPS) regulations for many new source categories. He joined ORD in December 1984 and was assigned responsibility for developing a suite of models capable of projecting national sulfur oxides for the National Acid Precipitation Assessment Program (NAPAP). After completing these models and the NAPAP assessment, he was selected for supervision of the Emissions and Modeling Branch, the predecessor of ECPB. Research produced by ECPB over the last several years has shown that (a) biogenic VOC emissions are massively large in many regions of the U.S. and (b) that heavy-duty trucks produced more emissions than standards allow. These findings have had a direct bearing on a change in regulatory strategy by EPA to emphasize nitrogen oxides emissions reductions for control of tropospheric ozone air quality. He is the former EPA chairman of the National Research Strategy for Tropospheric Ozone (NARSTO) emissions workgroup. ECPB is currently constructing a large new facility for testing emissions from medium and heavy-duty trucks and currently developing new open path measurement techniques for analysis of fugitive emissions using tomography methods. These methods are being applied to evaluation of emissions from Concentrated Animal Feed Operations (CAFOs).

Mr. Jones received his B.S. degree in Chemical Engineering from North Carolina State University in 1966.

Foy King

Mr. King has an associates degree in mechanical engineering. Foy has 26 years experience working with auto and truck emissions. He has a class A license with hazmat and twin endorsements.

John Kinsey

Mr. Kinsey has a B.S. in Biology/Physical Science from Central Missouri State University. He also certified as a Qualified Environmental Professional by the Institute of Professional Environmental Practice. His 30 years of experience includes the characterization and control of fine particulate matter (PM) emissions with employment in both the public and private sectors. Mr. Kinsey's current research interests include the characterization of the PM emissions from diesel trucks, residential wood combustion, and the fugitive dust emissions from construction activities. He has also recently completed a major research effort to determine the mercury emissions from chlor-alkali plant cell buildings.

Michael Kosusko

Mr. Kosusko received his Bachelor's in Engineering degree from Stevens Institute of Technology, Hoboken, New Jersey; and a Master's of Science in Chemical Engineering from the University of Virginia, Charlottesville, Virginia. He has worked for the U.S. Environmental Protection Agency for 14 years with the Air Pollution Prevention and Control Division and its predecessor organizations. Early during his career, he completed research and development on methods of controlling volatile organic compound (VOC) and air toxics emissions. For nine years, he has evaluated pollution prevention options for reducing emissions for solvent cleaning and surface coating operations. He is currently responsible for the Environmental Technology Verification Program (ETV) Coatings and Coating Equipment Pilot (ETV CCEP). ETV CCEP is being conducted cooperatively with Concurrent Technologies Corporation (CTC) at the Department of Defense's National Defense Center for Environmental Excellence in Johnstown, PA. He is also responsible for the Coating Alternatives Guide (CAGE), an electronic surface coating decision-making tool and information system.

Eben Thoma

Since joining the EPA in 2003, Dr. Eben Thoma research interests have focused on development of optical technologies for measurement of hazardous air pollutants (HAPs) and fine particles. He is also interested in the environmental benefits and implications of nanotechnologies. Dr. Thoma previously led private sector research efforts in instrumentation development and product characterization.
