Areas of Specialization: 

Sustainable Infrastructure



My overall aim is to advance scientific and engineering knowledge in the developing field of systems analysis for sustainable engineering. My primary area of research involves developing and applying life cycle assessment and techno-economic methods to evaluate the technical and externality impacts of conventional and alternative energy and transportation systems and elements of the built environment more generally. The research is interdisciplinary, incorporating civil, environmental, chemical and mechanical engineering, economics and public policy components to name a few. I collaborate with both the public and private sectors on the research projects.
