About Başak

Dr. Bektaş is an associate scientist at the Center for Transportation Research and Education. She serves InTrans as its resident statistical expert, applying statistical methods and data mining to a variety of transportation problems. With an interdisciplinary background and master’s degree in industrial engineering with a focus on systems management, her research experience covers infrastructure asset management with a focus on bridges, pavement and pavement markings, performance measurement, risk and reliability analysis, engineering economic analysis, and transportation safety.

Dr. Bektaş has served as the principal investigator on projects that address bridge management data and tools with the Federal Highway Administration, U.S. Department of Transportation, and Iowa and Minnesota DOTs. She chairs the Transportation Research Board’s AHD35 Bridge Management Committee and International Road Federation’s Asset Management Committee. She is a founding member of the AHD37 Bridge Preservation Committee and a member of the AASHTOWare Bridge Management Software Technical Review Team.
