Zoe G. Cardon is an American ecosystems ecologist focused on observing and understanding ecosystem interactions in the rhizosphere. She has also played an integral role in developing systems to better study the rhizosphere without digging it up and interfering with the ecosystems using stable isotopes and mathematical modeling. Cardon is currently a senior scientist at the Marine Biology Laboratory at the Ecosystems Center and an adjunct professor of ecology and evolutionary biology at Brown University. She is credited with helping to establish the National Microbiome Initiative at the White House Office of Science and Technology Policy in Washington, D.C.
