James E Parks II

Group Leader, Emissions and Catalysis Research

Dr. Parks leads the Emissions and Catalysis Research Group at the National Transportation Research Center at Oak Ridge National Laboratory. He received his B.S. in Physics from North Carolina State University in 1989 and his Ph. D. in Physics from the University of Tennessee in 1995. During his dissertation, Dr. Parks’ research focus areas were photon scanning tunneling microscopy in the ultraviolet and soft x-ray regions and novel photonics-type applications for materials analysis. Prior to joining Oak Ridge National Laboratory, Dr. Parks worked in the private sector at EmeraChem LLC, a small technology company specializing in lean NOx trap catalyst research and development and catalyst commercialization and production for power generation and automotive applications. His current research interests are emission control for lean burn and advanced combustion engines, catalysis for biomass to fuel processes, modeling of reactor systems, advanced spectroscopic technique development, and novel applications of nanophase materials. Dr. Parks has numerous publications in peer-reviewed journals. He is currently a member of the American Physical Society and the Society of Automotive Engineers, and he serves as a member of the Low Temperature Aftertreatment sub-team of the US DRIVE Advanced Combustion and Emission Control Technology Team.
