Jennifer Pett-Ridge

Dr. Jennifer Pett-Ridge is a Distinguished Member of the Technical Staff at LLNL, Adjunct Professor at UC Merced and a Principal Investigator of the UC Berkeley Innovative Genomics Institute. Dr. Pett-Ridge studies the microbiology and biogeochemistry of soil carbon cycling, and how to achieve CO2 removal (“CDR”) in agricultural soils. In her research, she uses advanced metagenomics, stable isotope tracing and computational modeling to make quantitative estimates of ecosystem processes. She leads multiple team projects for the US Department of Energy, including the Microbes Persist Soil Microbiome Scientific Focus Area, the DOE Terraforming Soil Energy Earthshot Research Center and the LLNL Carbon Initiative. Recently, she led a 68 member team and published Roads to Removal –a county-level assessment of CDR options in the USA. Dr. Pett-Ridge has co-authored over 150 peer-reviewed technical publications that have collectively received over 10,000 total citations. Pett-Ridge is a recipient of a DOE Early Career award (2014),  Geochemical Society Endowed Biogeochemistry Medal (2019), Secretary of Energy Achievement Award (2021), the DOE Office of Science Ernest Orlando Lawrence Award (2022), and the 2023 Deborah A Neher Career Award from the Ecological Society of America Soil Ecology Section.

Simon Pang

Simon is interested in development and implementation of materials and technologies for carbon dioxide removal, the interface between carbon capture technologies with carbon conversion to develop a circular carbon economy, and systems analysis for carbon removal and energy technologies. He leads DOE-funded projects spanning topics from fundamental investigations of direct air capture materials degradation mechanisms to development of hybrid reactive capture processes that integrate carbon capture and conversion. He leads the Direct Air Capture pillar of the LLNL Carbon Initiative.

Allegra Mayer

Allegra Mayer is a postdoc at Lawrence Livermore National Laboratory (LLNL), where she is analyzing the potential carbon dioxide removal contribution of agricultural soil management to help reach the national climate targets. Generally, her research is oriented toward understanding mechanisms for improved management of food-producing ecosystems to contribute to climate-change mitigation over time.  Allegra completed her Ph.D. in soil carbon biogeochemistry from the Silver Lab at University of California Berkeley.

Kimberley Mayfield

Kimberley (Kim) Mayfield is a member of LLNL’s 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.
