Dr. Southworth joined the Georgia Tech faculty in February 2012. Prior to joining Tech, Dr. Southworth spent 28 years as an employee of the US Department of Energy's Oak Ridge National Laboratory located in East Tennessee, leaving ORNL as a Distinguished R&D Staff member in December of 2011. Prior to joining ORNL in 1984 he was a faculty member in the Civil Engineering Department at the University of Illinois in Urbana-Champaign, and before that he was a research officer in the Institute for Transport Studies at the University of Leeds in England.Dr Southworth has published extensively on transportation planning topics, and been involved in the management of a number of large transportation data and modeling projects that have produced widely used datasets and software tools. While at ORNL he received a number of awards for his research contributions. Most of this research has been for federal agencies, including the Environmental Protection Agency, the Agency for International Development, and various branches of the Departments of Agriculture, Commerce, Defense, Energy, Homeland Security and Transportation. He has also carried out research for, among others, the National Science Foundation, the Transportation Research Board, the Brookings Institution, the Pew Center for Global Climate Change, the Tennessee Valley Authority, and the Georgia, New York, and Tennessee State Departments of Transportation. He regularly serves on regional and national review panels dealing with data, statistical and mathematical modeling issues in both freight and passenger transportation.
