James E Parks II

Section Head - Energy Efficient Manufacturing Sciences

Dr. Parks leads the Energy Efficient Manufacturing Sciences Section at Oak Ridge National Laboratory (ORNL). 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. Prior to joining ORNL, Dr. Parks worked in the private sector at EmeraChem LLC where he specialized in lean NOx trap catalyst research and commercialization for power generation and transportation applications. Upon joining ORNL, he conducted research on catalysis and emissions control for advanced combustion engines and renewable fuels at ORNL's National Transportation Research Center.  Dr. Parks has served as Group Leader for the Applied Catalysis and Emissions Research and Chemical Process Scale-Up Groups prior to his current role as Section Head.  His current research interests include catalysis for biomass to fuel processes, carbon capture and utilization, 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 a Fellow of the Society of Automotive Engineers and is a member of the American Physical Society and the American Chemical Society.  He currently serves in the following leadership roles in the U.S. Bioenergy Technologies Office: Principal Investigator of the Consortium for Computational Physics and Chemistry, Steering Committee for the Chemical Catalysis for Bioenergy Consortium, and Co-Lead of the High Temperature Conversion Task in the Feedstock-Conversion Interface Consortium.
