Corinne Scown is the Deputy Director for Research of the Energy Analysis and Environmental Impacts (EAEI) Division at LBNL, Vice President and founder of the Life-cycle, Economics, and Agronomy Division (LEAD) at the Joint BioEnergy Institute (JBEI), and Head of Sustainability at the Energy and Biosciences Institute (EBI). She holds a secondary appointment in the Biological Systems and Engineering Division at LBNL. Scown’s expertise includes life-cycle assessment, technoeconomic analysis, biofuels and bioproducts, air quality impacts of vehicle electrification, strategies for atmospheric carbon removal, and co-management of energy and water. She has led projects funded by the U.S. Department of Energy, California Energy Commission, California Air Resources Board, and Energy Biosciences Institute. She has led the development of online tools for TEA, LCA, and bio-based feedstock assessment, including BioC2G and the Biositing tool. Scown was awarded the ACS Sustainable Chemistry & Engineering Lectureship in 2022 for her work on TEA and LCA of emerging technologies and served as a member of the National Academies of Sciences, Engineering, and Medicine’s Committee on Current Methods for Life Cycle Analyses of Low-Carbon Transportation Fuels in the United States. Scown earned a B.S. in civil engineering with a double-major in engineering and public policy at Carnegie Mellon University, and she received her Ph.D. and M.S. in civil and environmental engineering at UC Berkeley.

Kimberley (Kim) Mayfield is a member of LLNL’s Energy Group and principal investigator for Lawrence Livermore’s Energy Flow Charts (https://flowcharts.llnl.gov). Kim works with the Carbon Initiative, which aims to understand, develop, and implement technologies for the removal of carbon dioxide from the atmosphere. Her areas of focus are carbon accounting for carbon sequestration projects and environmental justice analysis for negative carbon emissions projects. Her research background is in environmental chemistry, with an emphasis on non-traditional stable isotope geochemistry in hydrologic systems. Prior to joining LLNL, Kimberley worked in the algal biofuels industry, innovating safe and economically viable ways to extract valuable products from microalgae.

Allegra is generally interested in the potential for carbon sequestration in soil to mitigate climate change. Her research includes modelling potential warming reduction from global scale improvements in agricultural land management, modelling the effect of compost application to soil organic carbon in California grasslands.
