Profile:

After receiving her B.S. in Environmental Science, Sharon volunteered for one term of service with the泭.泭She was stationed in Charleston, South Carolina and traveled with a team of thirteen people to seven states in the Southeast region of the Unites States doing service projects in the areas of education, the environment, and unmet human needs.泭She then worked for nearly two years as an environmental technician in San Diego, California, helping to remediate soil and groundwater contamination from leaking underground gasoline and diesel storage tanks. Subsequently, Sharon worked for three years as a middle school science teacher in San Diego and earned a California Teaching Credential in Chemistry from National University. She then taught International Baccalaureate Environmental Systems to high school students in Quito, Ecuador for two years before beginning graduate studies at Carnegie Mellon University in Pittsburgh, PA. She has been an Assistant Professor in the School of Economics since 2011, and was recently promoted to Associate Professor in 2018.
Sharons research is interdisciplinary in nature and centers on the technical, economic, environmental and social tradeoffs inherent in the production, distribution, and use of energy. She uses engineering-economic analysis, environmental life cycle assessment, social benefit-cost analysis, and multi-criteria decision analysis to assess tradeoffs in energy decision-making. She is interested in all energy options that have the potential to lead to a more sustainable energy future. Her particular expertise is in concentrated solar power, molten salt thermal energy storage, distributed solar thermal and photovoltaics (PV), drop-in cellulosic biofuels from woody biomass, hydropower, and community-based energy initiatives (especially solar and energy efficiency window inserts). Her research team created a database of泭.
