Lawrence Livermore National Laboratory, US
Jennifer Pett-Ridge is a senior staff scientist and group leader at LLNL who uses the tools of systems biology and biogeochemistry to link, identity, and function in environmental microbial communities and pioneered the use of NanoSIMS isotopic imaging in the fields of microbial biology and soil biogeochemistry. As lead scientist of the LLNL Genomic Science Biofuels Scientific Focus Area (SFA) (2009–2018) and more recently the LLNL Soil Microbiome SFA, she leads multi-disciplinary teams that integrate biogeochemistry, stable isotope probing, NanoSIMS imaging, molecular microbial ecology, and computational modeling to understand biotic interactions and energy flow in microbial communities critical to soil nutrient cycling and sustainable biofuel production. Pett-Ridge is currently leading a county-level assessment of options for carbon dioxide removal in the USA. She is the group lead for the Environmental Isotope Systems group at LLNL and manages a large portfolio of DOE, NSF, NASA and foundation support. Pett-Ridge has published over 120 peer-review articles, has received a DOE Early Career award, Secretary of Energy Achievement Award, the Geochemical Society Endowed Biogeochemistry Medal, and the DOE Office of Science Ernest Orlando Lawrence Award.
