Jennifer Pett-Ridge is the lead author of Roads to Removal, a comprehensive assessment designed to help the United States identify pathways and opportunities to reach carbon neutrality by 2050.  She is a Distinguished Member of the Technical Staff at Lawrence Livermore National Laboratory (LLNL), a federally-funded, multi-disciplinary science and research facility in California.  She is also an Adjunct Professor at the University of California Merced and a principal investigator of the University of California 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. She 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.
