Geology - Isotope Geochemistry - Paleoecology
Our research centers on understanding how terrestrial landscapes and organisms respond to past climate change.
We primarily use stable isotopic records to study interactions between mammals, vegetation, and climate in past ecosystems. Our work involves a combination of geologic fieldwork, isotopic labwork and modern analog studies. 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.
