Dr. Billy M. Williams is an Associate Professor in the Department of Civil, Construction, and Environmental Engineering at North Carolina State University. Previously he served as Assistant Professor in the School of Civil and Environmental Engineering at the Georgia Institute of Technology in Atlanta. Before beginning his academic career, Dr. Williams spent over five years as a consulting engineer with the firm of Kimley-Horn and Associates and four years as a commissioned officer in the U.S. Navy Civil Engineer Corps.

Dr. Williams is a recognized expert in the areas of analytical and simulation modeling of traffic operations and transportation networks, intelligent transport systems, and the application of rigorous statistical methods to a broad range of transportation modeling applications, including traffic condition forecasting and models of fundamental traffic flow characteristics. During his thirteen year academic career he has served on nearly fifty graduate student committees, chairing fifteen of these committees. Of the fifteen graduate students Dr. Williams has supervised as committee chair and research advisor, six have successfully completed their doctoral degree. He has published over 30 refereed journal and conference proceeding articles and generated over $3.5M in external research support. Funding for Dr. Williams' research program has come from a variety of sources including NSF, NCHRP, SHRP2, and the North Carolina Department of Transportation.

Dr. Williams serves on the Transportation Research Board (TRB) Committee on Statistical Methods and served many years on the Committee on Artificial Intelligence and Advanced Computing Applications. Through these committees, Dr. Williams has provided leadership through development of research problem statements and organization of multiple workshops and special sessions on statistical methods and modeling. He is currently chair of the ASCE Transportation and Development Institute's Advanced Technologies Committee. Dr. Williams was co-author of a book on coastal evacuation modeling and analysis and sole author of the chapter on "Intelligent Transportation Systems" in UNESCO's Encyclopedia of Life Supporting Systems and the chapter section on "Time Series Analysis" in the National Academy of Science's Scientific Approaches for Transportation Research: Volume II - Design, Analysis and Interpretation.
