Kimberley (Kim) Mayfield is a member of Lawrence Livermore National Lab’s (LLNL) Energy Group and principal investigator for Lawrence Livermore’s Energy Flow Charts. 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.
