More Experts


Constantine Samaras is an assistant professor in the Department of Civil and Environmental Engineering at Carnegie Mellon University (CMU). He is also an adjunct senior researcher at the RAND Corporation and a professor at the Pardee RAND Graduate School. His research spans energy, climate, and defense decisionmaking. Samaras analyzes how policy actions and research and development (R&D) investments affect energy use and national security, infrastructure requirements, economic and innovation outcomes, and life cycle environmental impacts. He served on a National Academies Committee evaluating the Department of Energy's advanced transportation energy research portfolio, serves on the Transportation Research Board's Alternative Transportation Fuels and Technologies Committee, and is an editorial board member of the journal Renewable and Sustainable Energy Reviews. He has published numerous studies examining plug-in and autonomous vehicles, renewable electricity, conventional and low-carbon fuels, and the industrial capacity of the evolving energy sector. Samaras has also led analyses on energy security, strategic basing, and infrastructure issues faced by the Department of Defense. He was previously a senior engineer at RAND, a post-doctoral fellow in the Climate Decisionmaking Center at CMU, and was earlier employed for five years as an engineer working on several multibillion-dollar infrastructure megaprojects in New York.

Samaras received his Ph.D. in engineering and public policy and civil and environmental engineering from CMU. He also is a Leadership and Excellence in Environmental Design (LEED) Accredited Professional in Building Design and Construction.

    As U.S. Energy Booms, Don't Forget About Roadway Infrastructure

    Natural gas production is growing and many states and communities are reaping the economic benefits. One of the costs, however, will be damage to roads. One hydraulic fracturing operation requires about 600 to 1,100 one-way, heavy truck trips to bring equipment, materials, and sometimes water to and from a well site.

    Transitioning to a Carbon Tax Credit

    Instead of setting an arbitrary Production Tax Credit value, we could provide a tax credit based on the social value of clean electricity generation, writes Constantine Samaras.
