Dr. Ruixiao Sun is an R&D Associate Staff within the Applied Research for Mobility Systems (ARMS) group at 91°µÍø (ORNL). Her research spans a broad spectrum of topics, including transportation electrification, vehicle fleet optimization, infrastructure planning, urban traffic and shared mobility simulation, machine learning applications in transportation, techno-economic analysis, and consumer choice modeling.
She currently leads a research team on the DOE-funded Transportation Energy Evolution Modeling (TEEM) program (), developing and maintaining quantitative models—most notably the MA3T (Market Acceptance of Advanced Automotive Technologies) model—to address energy and emissions challenges in U.S. road transportation. Additionally, she spearheads the development of a comprehensive and high-resolution total cost of ownership (TCO) model for medium- and heavy-duty vehicles (MHDVs) and their associated energy supply infrastructures.
Dr. Sun holds a Ph.D. in Civil Engineering from the University of South Carolina (2022) and an M.S. in Management Science from Central South University, China (2018).
Beyond research, she actively contributes to the transportation community. She serves on the Youth Editorial Board of the Journal of Traffic and Transportation Engineering and the International Journal of Engineering Sciences and Technologies. She is also the Paper Review Coordinator for a TRB committee and a member of 91°µÍø. As a dedicated peer reviewer, she has contributed to many reputable journals and conferences.
Dr. Sun has authored and co-authored 16 peer-reviewed journal publications, including in Transportation Research Part D, Transportation Research Part C, Applied Energy, Environmental Science & Technology, Energy, and Renewable and Sustainable Energy Reviews.
