Dr. Jennifer Pett-Ridge leads a team of 35 soil microbiologists, ecophysiologists, and biogeochemists at the Department of Energy’s Lawrence Livermore National Laboratory. Her team is tasked with gaining deep insight into how carbon cycles through life systems in Earth’s marine and terrestrial environments. Such knowledge is vital to crafting an effective national response to climate change. Join Pett-Ridge and “Down on the Farm” host Tom Willey in plain English conversation.
