Dr. Scott Curran is a research and development staff member in the Fuels and Engines Research Group at Oak Ridge National Laboratory (ORNL). He leads the advanced compression ignition experimental research including the development of advanced combustion concepts and investigating the fuel effects on advanced combustion modes. The findings from this pre-competitive research have led to more than 38 peer-reviewed publications with more than 715 citations. . He is also involved in vehicle systems research projects, well-to-wheels analysis for mobile and stationary power sources, the ORNL Sustainable Campus Initiative and is an active collaborator with DOE Clean Cities for alternative fuels and advanced vehicle technology outreach and education and serves on the board of directors for the East Tennessee Clean Fuels Coalition. He served as the vehicle lead for the ORNL Additive Manufacturing Integrated Energy (AMIE) project where ORNL 3D-printed a working range extender vehicle and a small house which share energy. Scott's technical socieity involment includes being the vice-chair for the SAE Combustion Committee and incoming chair, and is a co-founder of a new symposium on range extenders for electric vehicles in addition to be a session orginizer and reviewer. Scott is an elected member of the ASME internal combustion engine division (ICED) and a judge for the ICED undergraduate poster presentation competition. He received his BS and MS in mechanical engineering from the University of Tennessee – Knoxville (UT). He completed his PhD degree in Energy Science and Engineering in 2014 within the UT/ORNL Bredesen Center becoming one of the first of two graduates from the program.
