Renewable Energy, Sustainable Energy Economics & Policy, Environmental Impacts of Energy, Thermal Energy Storage, Energy Poverty, Multi-Criteria Decision Making
My research is interdisciplinary in nature and centers on the economic, environmental and social tradeoffs inherent in the production, distribution, and use of energy. I use engineering-economic analysis, environmental life cycle assessment, social benefit-cost analysis, and multi-criteria decision analysis to assess tradeoffs in energy decision-making. My primary expertise is in concentrated solar power, thermal energy storage, and distributed solar energy generation. However, I am expanding my research to include other renewable energy technologies, especially solar distributed generation (water/space heating and PV), biomass and wind. I am particularly interested in comparisons between central and distributed generation renewable energy options – especially community-managed strategies. I am also beginning some research on environmentally-economically sustainable waste management.
After receiving my B.S. in Environmental Science, I volunteered for one term of service with the Americorps National Civilian Community Corps (http://www.americorps.gov/about/programs/nccc.asp). I 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 projects in the areas of education, the environment, and unmet human needs. I 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, I worked for three years as a middle school science teacher in San Diego and earned a California Teaching Credential in Chemistry from National University. I then taught International Baccalaureate Environmental Systems to high school students in Quito, Ecuador for two years before beginning graduate studies.
My doctoral research was about the environmental and economic implications of thermal energy storage for concentrated solar power (CSP) plants. I created an integrated assessment model (IAM) that calculates the annual capacity factor, levelized cost of energy, life cycle greenhouse gas emissions, water consumption and land use of a parabolic trough CSP plant with three different energy backup systems and two cooling options. The IAM uses a multi-criteria decision analysis framework to assess the tradeoffs between different backup systems and cooling technologies in order to develop policy recommendations. This research was funded by the National Science Foundation’s Graduate Research Fellowship and the Climate Decision-Making Center at Carnegie Mellon University.
I have a Maine Agricultural and Forest Experiment Station appointment to research renewable energy in Maine. I am currently working on assessing economic, social, environmental and policy barriers and opportunities to widespread distributed solar energy deployment in Maine (PV, water and space heating applications). I am working on a paper that compares the sustainability of a variety of renewable and non-renewable electricity options for the U.S. through a multi-criteria decision analysis framework. I am also part of the new National Science Foundation (NSF) Sustainable Energy Pathways group that is examining an economically, environmentally and socially sustainable pathway for developing drop-in biofuels from woody biomass. I am working with the Advanced Structures and Composites Center at UMaine to develop a levelized cost of energy estimate for a new floating offshore wind farm in the Gulf of Maine. I received a University of Maine Pre-Tenure Research and Creative Activity Fellowship in order to develop a 2014 NSF-CAREER grant proposal for a Sustainable Energy Research Program. I am also working on a project that estimates the economic implications of a variety of landfill development scenarios in the mid-coast region of Maine.
