Scott's work intends to facilitate infrastructure  and policy decision making under uncertainty via innovative large datasets, computation, and visualization methods. His primary current interests are in the area of transportation and society, by studying fleet energy use and the benefits of improved program management of safety and emissions inspection systems. He has previously contributed to development of research and education tools for environmental and energy life cycle assessment of products and processes (such as the EIO-LCA model), estimating and tracking environmental effects across global supply chains (such as carbon footprinting), and the sustainability of infrastructure systems.


  • Ph.D. (Economics) 1999, Carnegie Mellon.
  • M.S. (Economics) 1996, Carnegie Mellon.
  • B.S. (Computer Engineering/Engineering and Public Policy) 1992, Carnegie Mellon
