Class of 1996 Department of Microbiome Science, Max Planck Institute for Developmental Biology
Ruth's awards include the NIH Director's New Innovator Award and a Packard Fellowship for Science and Engineering. In 2015, she was named director of the Max Planck Institute for Developmental Biology in Tubingen, Germany. The Ley Lab studies the microbiome of mammals and plants, its role in host health, and how the host can shape microbiome diversity.
The Diefendorf Lab continues to make progress at the interdisciplinary intersections of plant ecology, geology, and climate. A recent publication shows that deeply buried paleosols have been found to be rich in carbon, adding a new dimension to our planet’s carbon cycle, and revealing the possibility that soil disruption could contribute to global climate change.
Jim Randerson’s lab has emerged as one of the premier carbon cycle modeling groups working at regional to global scales. An important research goal is to quantify how the contemporary global carbon cycle is changing and to assess the implication of this change for stabilizing atmospheric greenhouse gases levels and climate. In 2017, Jim was elected to the National Academy of Sciences.
The Beman Lab studies marine biogeochemistry, especially nitrogen cycling. In a PNAS study of oceanic systems, Michael and colleagues demonstrated that microbial nitrification rates decreased in response to the decreases in ocean pH associated with ocean uptake of anthropogenic carbon dioxide emissions.
