This episode is the third in our new oral history series, In Their Own Words. These pieces chronicle the stories of scientists who have made great contributions to their fields, particularly within the biological sciences. Each month, we will publish in the pages of BioScience, and on this podcast, the results of these conversations. Today, we are joined by Dr. Diana Wall, university distinguished professor, director of the School of Global Environmental Sustainability, and professor in the Department of Biology, at Colorado State University. She previously served as president of the American Institute of Biological Sciences. Note: Both the text and audio versions have been edited for clarity and length. Read this article in BioScience.
