Summary
With a strong interest in a wide range of environmental and energy issues, Chris is excited to be working at the Institute of Transportation Studies at UC Davis. He obtained his PhD (June 2003) from Princeton University, where his research (in collaboration with the Departments of Chemistry and Chemical Engineering) focused on fuel cell polymer membranes. He also worked closely with the Center for Energy and Environmental Studies (now part of Princeton Environmental Institute). His undergraduate and master's degrees focused on biology, environmental science and engineering. Chris is now working within the Hydrogen Pathways program at ITS on analyzing economic and environmental implications of a variety of energy pathways and is a Track director for the Infrastructure Modeling Track.
Hydrogen Pathways Research Interests
Regional Analysis and Evaluation of H2 Infrastructure – Chris is working on understanding issues related to the evolution of the hydrogen economy on a regional and geographic context. Major work includes developing simplified H2 pathway models for hydrogen production and distribution and optimizing economics and location of production facilities and distribution networks using GIS.
Interactions between Hydrogen and Electricity Production in a California Hydrogen Economy – This project focuses on identifying and understanding the integration and interactions of hydrogen and electricity production in a developing and mature hydrogen economy. Issues include co-production strategies, competition and coincidence in timing for primary energy feedstocks and environmental and economic implications.
His interests also encompass renewable resources in the context of H2 production and alternatives uses.Research Docket
