Voss Postdoctoral Research Associate in Environment and Society


Lina C. Pérez-Angel’s research in paleoclimatology has contemporary relevance. During the Pliocene, between 5 and 2.5 million years ago, Earth’s atmosphere had about 400 parts per million of carbon dioxide—pretty similar to what we have now. She uses bacterial lipids and other biomarkers on rocks to see how ancient rains, droughts, and temperatures affected the environment then and compares the results to recent data to see how these processes were different from what is happening now.
