Noah Planavsky

Noah Planavsky is an isotope geochemist who works on environmental change in Earth’s past, present, and future.  Planavsky’s work combines field studies, analytical chemistry, novel isotope systems, and geochemical modeling. He has extensively researched atmospheric evolution—particularly changes in oxygen and carbon dioxide concentrations. Current projects focus on changes in ocean oxygen levels, tracking how primary productivity has changed through time, and on the potential for carbon capture through enhanced mineral weathering in marine and terrestrial environments.
