Paul Newsome Leiby

Team Leader, Distinguished Research Scientist


Paul Leiby is a Distinguished Research Scientist at Oak Ridge National Laboratory. He manages ORNL’s Fossil Fuel Modeling program and leads the Energy Analysis Team for the Environmental Sciences Division. Prior to ORNL he was a research fellow at Harvard University's Energy and Environmental Policy Center. Recent research topics include the economic analysis of advanced vehicle technologies, vehicle automation, and alternative motor fuels, energy security and oil market modeling, the evaluation of emergency oil stockpiling policies and greenhouse gas emission policies.

Paul is the current Chairman of the Transportation Research Board's Transportation Energy Committee and a former member of the TRB Alternative Fuels Committee. He has served on professional groups such as the Energy Modeling Forum’s panels on World Oil Modeling and Energy Security and on advisory groups for the U.S. National Academy of Sciences, the Governmental Accountability Office, and the Office of Technology Assessment. He received his Master’s Degree in Public Policy from Harvard University and his Baccalaureate Degree from Harvard College.
