Dr. Hanna Breunig is a Research Scientist in the Sustainable Energy Systems Group in the Energy Analysis and Environmental Impacts Division. She holds a secondary joint appointment in the Earth Systems and Society Domain in the Climate and  Ecosystem Science Division. Hanna specializes in spatially- and temporally-resolved environmental, human health, and economic impact assessment of emerging energy and wastewater treatment technologies. These include waste-to-energy/resource systems, bioenergy, distributed generation, and gas (H₂, CO₂, CH₄) capture, utilization, and management technologies. Currently, she is collaborating with a team of scientist in ETA to develop a roadmap for sustainable, cost-effective utilization of waste biomass for distributed energy generation in California. She holds a B.Sc. in Environmental Engineering from Cornell University and an M.Sc. and Ph.D. in Civil and Environmental Engineering from UC Berkeley.
