Sarah Hernandez received her PhD in Civil and Environmental Engineering with a specialization in transportation systems engineering from the University of California, Irvine.  She holds a M.S. from the University of California, Irvine (Irvine, California) and a B.S. from the University of Florida (Gainesville, Florida).   Dr. Hernandez joined the University of Arkansas Civil Engineering Department in August 2015.  She teaches graduate classes on transportation planning and transportation data analysis.  Dr. Hernandez is the faculty advisor for the student group, Transportation Leaders for the 21st Century (TL-21) which includes the student chapter of the Institute of Transportation Engineers (ITE).  Her research focuses on new and advanced technology applications in transportation systems engineering and is centered on developing tools and methods to collect and analyze freight and commercial vehicle operations data for long range freight planning.  She serves as a member of the Transportation Research Board’s Standing Committee on Freight Transportation Data (ABJ90) and is the Committee Research Coordinator for the Workforce Development and Organizational Excellence (AJE15).
