Biography
Publications
  • Naomi Levin is a geologist whose research centers on understanding how landscapes and terrestrial organisms respond to past climate change. She primarily uses stable isotopic records to study interactions between mammals, vegetation, and climate in past ecosystems. Her research involves a combination of geologic field work and stable isotope laboratory work. Active projects include reconstructing Plio-Pleistocene environments from sedimentary and isotopic records preserved in the East African rift, isotope hydrology in Ethiopia, paleoecological and sedimentology of mid-Pleistocene sites in South Africa, and mass-dependent Δ17O variation in the sedimentary record and the hydrosphere.
