I develop methods and software for preservation and management of structural assets of surface transportation networks. Research sponsors include the National Academies, the American Association of State Highway Transportation Officials, the USDOT Federal Highway Administration, and the State of Colorado Department of Transportation. Current work will develop guides to preservation of highway bridges and measurements of performance of surface transportation assets. I prepare scholarly reviews of state-of-the-practices in structure preservation and management. These reviews are used to direct national research programs and to guide policy development in state and federal governments.
