Departments of Civil and Environmental Engineering / Engineering and Public Policy

Member, Green Design Institute 

Areas of Interest

Scott's work intends to facilitate infrastructure and environmental decision making under uncertainty via large datasets, computation, and visualization methods. He has 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.
